I bought one of the 75 led strips from Dealextreme without knowing exactly what I wanted it for:-

Also happened upon these so got 2, one for the car and one for the bike:-

So looking at the bike I started thinking about how I could use the led strip and the flasher. First I though I'd make a light to go under the tail light, but thought that would be ugly. I noticed the ends of the tail light did nothing, and sure enough there's big empty spaces at each end, The LED strips can be cut into 9 led lengths. Two of these fit side by side in each side of the tail light like this:-



Silasticed it all in. Here's the brake light flasher all wired in. It is incredibly small and potted in resin so is totally waterproof:-



As the original bulb is still in it has no effect on the BMU but the outer 2 ends of the the tail light flash then stay on, you can change it to how you want it to flash. I have it set up to flash quickly 4 times then stay on, then if you release and reapply the brake within 20 seconds it doesn't flash. This is so it doesn't annoy drivers behind in traffic.

What I have noticed mostly is how slow the bulb actually lights up! I reckon it takes about a quarter of a second!! Now the leds light up instantly and if the normal bulb ever does blow I have a backup stop light.

Works really well!

Thanks for the report, getting more light back there is definitely a good thing! How exactly did you do the wiring?

Here you go, sorry about the quality, I don't have the right stuff to do proper circuit diagrams.

BTW because the BMU trickles a tiny bit of current into the bulb, the flasher circuit thinks the brakes are on if you have the bulb out so won't flash, so you have to do the testing and setup with the bulb in to drag the bulb positive to ground when it's off. Does that make sense!!

I hope the drawing is clear enough!

Hey that's pretty cool, but it took 4 beers to work out how to use it!!

So I have it drawn as a pdf but no idea how to post it here except take a photo of it. But my printer has no ink so can't do that till tomorrow at work.

Yes the BMU is the Bulb Monitoring Unit. It was easy enough just to put the bulb in but yes a 12k resistor would certainly work. I could reach the bulb but would have had to walk to the other end of the house to find a resistor Way too lazy for that!!

Hey Ted, perhaps we should allow attaching certain files like PDF, KMZ (Google Earth locations) and others, just not picture, leave those as links.

Cheers

Maybe you could send it to Drake and he could place it among his other documents in the stickies.
