See and Be Seen - Singapore’s First Night Cycling Safety Campaign

Yet another cycling project by students of NTU's Wee Kim Wee School of Communication and Information - this time Grace Auyong write to introduce us to See and Be Seen, Singapore’s First Night Cycling Safety Campaign, which is a 30km ride night ride on 10 March 2012 which begins at 10pm at Xtreme Skate Park @ East Coast Park.

"See and Be Seen is our tiny effort to raise awareness about the need for visibility while cycling at night. As you know, cycling in Singapore is steadily increasing in popularity. Night cycling is particularly popular with the busy folks in Singapore, with the weather, and the traffic being more favorable to cyclists at night. However, many of these casual cyclists do not take note and use essential cycling safety equipments, when they head out to cycle.

This is where See and be Seen comes in. We plan to encourage more to be visible while night cycling through Facebook (http://www.facebook.com/seeandbeseen), and also through our Night Ride on the 10th of March. The ride will start at 10pm, and continue till 2am. It will be a 30km night ride, where 250 participants will learn more about night cycling visibility, and pick up other tips and tricks of night cycling safely."

Registration points:

• Ride date: Sat 10 Mar 2012: 9pm - 3am from ECP
• Register by 01 Mar 2012
• $15 registration; you will receive an event t-shirt (pick up on 03 Mar 2012) and ride kit (after event)
• A bike rental package at $10 for a standard mountain bike has been arranged with shop next to event start point.
• Organiser will return your packaged rental bike with your bike receipt at the end point.
• Park at ECP Car Park F1

I am enthusiastic about being brightly lit, to increase my visibility and lowering risk of an accident and write about this a year ago in "How brightly lit are you? Tail lights and other stories"

This morning, a fellow cyclist I see almost every year at the NTU Bike Rally, send me this news release about BLAZE, a light projection devise to alert drivers about your presence in congested cities, especially those who might not see you when pulling into your lane. Emily Brooke of University of Brighton suggested,

"Even when lit up like a Christmas tree a bicycle in a bus's blind-spot is still invisible."

- Lighting the way." University of Brighton News and Events, 01 Jun 2011.

This reminded me of something I came across a few months ago. It projects a lane definition to the rear of a bike possibly for use with night rides. Designed in Singapore, it's called Laser Lite Lane

Would you use any of these? I guess we'd have to see this in action or try it first. Green Idea Factory, however, is quick to argue against these, with a cautionary post last year: "Don't believe the Hyper-illumination".

Certainly adequate, blinking illumination should be a requirement for all cyclists on the road and I hardly think BLAZE will be the solution to city traffic collision woes.

I am not a cycle to work guy, so I avoid peak hours and practise defensive riding - origins I credit to the theory lessons for my motorcycle 2B license by some very experienced ex-traffic cops in the late 80's.

This is important because cyclists in Singapore are in no man's land in public roads - we are in a "ride at our own risk" situation. So I ride like a prey species, am unlikely to battle for a lane with a larger vehicle and am alert to pre-empt interactions. I watch motorists like a hawk, am situationally aware and happy to compromise speed for safety in an instant, even choosing alternative and longer routes to avoid messy spots.

Cycling in dense urban traffic has its own joy and requires specific bursts of acceleration, clear and early indication of intention, steady riding and confluent with the flow of traffic, complete attention and alertness. One indication of success - cars aren't honking you. But I've pretty much given that up these days. I like the PCNs and smell of fresh air too much.

The lack of bicycle lights on an early Sunday morning

As I cycled down past MacRitchie last Sunday morning, I was struck with the sight of a roadie who overtook us - she had neither lights nor reflectors.

Despite it being a weekend, there was still plenty of traffic at 7am. Lights and a colourful jersey are critical for road safety especially in the early morning light.

How brightly lit are you?

How brightly lit are you? Tail lights and other stories

My friends and I in Zendogs try to ride safely and probably since I spend the most time in heavy traffic, I am the most concerned. My getup reflects this:

Bright, flashing lights - front and rear

Amongst other factors and some good luck, lights are a significant part of keeping safe in both day and night. I have always been willing to fork out cash for lights which help keep me safe. And I have been surprised when some cyclists are hesitant about doing likewise. I am puzzled when cyclists on expensive racers speed by on an early morning ride, just as poorly lit as the foreign worker on some ramshackle bicycle, who is always held up as the epitome of the unsafe cyclist.

The lack of demand for good lights by local cyclists has meant a limited range in neighbourhood bicycle shops. We used to travel to specific shops from word of mouth recommendations just to get a particular type of light. Eventually, more of us travelled overseas for work and internet purchasing became easier and good lights were no longer inaccessible.

I suspect with the greater effort at highlighting road safety advocacy in recent years (see this SSC booklet), there has been an improvement and more cyclists have geared up with lights. And with the greater demand, some local shops are stocking pretty good lights. An example can be seen in this recent discussion on rear lights in local cycling forum Togoparts.

My staple light for about a decade now has been a Planet Bike Blinky 3H Helmet Mounted Rear Light - we bought extra for most of my cycling kakis, the Zendogs, as a helmet-mounted light significantly improves a cyclists' visibility. Variously I have had a 4-LED Sigma Cuberider and a 5-LED Cateye TL-LD610, happily replaced by a friend when the previous one went kaput. Add to the mix fully charged batteries each time I emerge for a ride and I'm visible!

I read with great interest that Sigma Cuberider now has a version II with five LEDs and 2 x AAA batteries instead of single size N battery. I have to get that!

Weak batteries can eliminate the effectiveness of your best lights, so my kakis and I will report on each others' roadworthiness, e.g. my comments here:

"Ladybug had her three rear lights on the way down to ECP last Sunday and she could be easily seen from far She had on a Planet Bike helmet rear light and that really great Sigma Cuberider with the odd-size N battery that was popular about four years ago plus *drum roll* a "no-brand" red flashing light on her back from a retired Citicab driver, courtesy of his daughter - Citicab apparently gave it to drivers in case of breakdowns and it's very bright!

In contrast, I could not see another rider who had just one weak light on her seat post. Guess she needed to change the batteries!"

A Zendogs conversation

On 20-21 Mach 2009, I chatted with my fellow cycling kakis about tail lights which I reproduce here for a quick impression on rear tail light options (US$ values link to the relevant Amazon Store pages). If you have recommendations, know of local shops selling such lights and local prices, do pitch in with comments - thanks!

"I've been looking at bicycle tail lights and was thrown off by the lingo which prevents direct comparisons, candlelight, lumens and wattage.E.g. this Cateye chart uses candlepower.

Without any consideration for weight, battery life, battery type or cost, these top contenders emerged very quickly:

NiteRider Cherry Bomb
Great reviews, a new light on the market. US$25.

Planet Bike Blinky Super Flash
Also very popular and has a white version for the front - US$19.

Other contenders

Blackburn Mars 4.0
LED's: 1w Ultra Bright Red, 2 amber side. US$25.

Marpac Foxfire
LED's: 26 "Super Bright", 360º Illumination. US$25.

"Hi Siva,

The units measure different things (lm, W, and cd) and conversion between lm and cd is possible if you know the solid angle of radiation. Between lm and W, you can also convert but this may not be an entirely realistic conversion as it is based on one wavelength only and may be affected by other items such as efficiency and optical characteristics of the housing/lens.

Anyway, with lights, if they can give the units to you in cd (or mcd – thousandth of a candela), that would be sufficient. The one below is a good one. Guaranteed that you would be seen from far away as the leds are spaced out over several angles.

Cateye TL-LD610 (5 red LEDs)

For lights with LEDs and units in Watts, anything more than ½ W to 1 W is bright enough. However, this unit just refers to the power required by the LED to generate the brightest possible output. Does not take into account the optics of the plastic housing or lens. So if your lens or housing is badly designed (or say scratched), that maximum brightness seen by an observer will be reduced accordingly.

In our riding conditions, after settling for the brightness of the light, I would also take a look at dispersion angle for visibility, environmental protection (IP rating or waterproofness), and battery life."

"The angles on the Cateye TL-LD610 (3 x AAA) are why it is my sole tail light now (apart from the Planet Bike helmet-mounted rear light) - a wider view might be offered by the Nite Rider Cherry Bomb.

I have the Cateye strapped on to the left seat stay since the gear cable runs along the right. This light is thus viewable at a distance but only from left-approaching vehicles.

For rIght-approaching vehicles I am relying on reflection by my bright-coloured cycling jersey and ankle straps. Proximal alerts will otherwise come from the helmet light. So adding a below-saddle tail light angled to the right will help.

The other thing I am looking for is a small, white light for the helmet now. But that's another story."

"I have the Planet Bike 1/2 watt Super Flash and I love it. The flash pattern is very distinctive and draws attention. For a little one, it packs a powerful flash. The roads here (Wilmington, NC, USA) tend to be unlit and it gives me confidence to commute at night. Currently my front light is the Planet Bike Blaze 1 watt. Good stuff."

Sivasothi wrote:

"Planet Bike supports bicycle advocacy and their lights were good, so our lights were all Planet Bike when Ladybug got them in Canada. Busted most of them since! But they were not as strong as our current lights.

From what I read, the Super Flash is one of the lightest at that power rating, so the weight freaks will love it for this as well."

Note: There is some suggestion that the Taiwanese SMART light I have see on sale in several stores these days may be the OEM version of Planet Bike's Blinky Superflash. They certainly look alike! For sure this too strong for a group ride except for the "last man" to use.

What about headlamps?

There are two types of front lights - flashing front lights to alert others to your presence and constantly-lit headlamps which help light your way. I am rarely in significant darkness so have never really explored headlamps. Flashing front lights are a critical part of any cyclists gear and the light and movement help to announce your presence to other road users. I have been reasonably satisfied with a 5 LED, 170 cd (at centre of light) Cateye HL-EL210/220 which I bought for about $55 one night before heading into the Coastal PCN. It was real handy!

There are the much brighter HL-EL-320 (1004 cd centre) or the lighter and waterproof HL-EL450 (400 cd centre; 3 x A3 batteries so half the battery life) - the latter costs US$34 and has a swivel mount which you can direct sideways, a useful option when cycling past junctions with vehicles turning in sideways to cut across your lane.

Besides Cateye, there is Sigma with Cubelight II and many others as well as Planet Bike's US$19 Blinky Superflash Tail Light (comes in white) or the US$65 Topeak WhiteLite HP 3-Watt Bicycle Light.

WhIle I want to be able to grab attention adequately from amongst traffic, I don't want to blind fellow road users temporarily. I would like to evaluate my light coming from a distance amidst traffic to determine its effectiveness at alerting an oncoming driver.

On the other hand, already at this light's intensity, I am careful to prevent blinding pedestrians when I join a PCN by switching the light to constant mode (i.e. not blinking) and pointing it downwards.

For the rare occasions I do need a headlight to light up my path, this US$60 Cateye HL-EL530 LED Bicycle Headlight looks like an attractive option. It is 100g heavier than my current light but is waterproof and the centre of beam is about 10x brighter at 1658 cl. – gosh, why don't I already own this?

Ride safe everyone!
