LEd Lights, the fun way

So I got those 1 watt led lights, so far just hooking them to battery and pointing across road. They light up fence a bit with lots of streat lights so rather impressed impressed. But lets face it these thigns (http://www.plasmaled.com/high_power_module.htm h) arn't black and don't have mounting brackets. Also my bike is on a all black diet, even the reflective tape is black . So off to princess auto I go, and found these driving lights (http://www.princessauto.com/surplus/...driving+lights) which also have a neon green ring that lights up around the light COOOL, useless but cool bling bling. But more importantley they are big enough for the led lights to fit in, are all metal and all black. So back home and its time to break out the mill, make a hole for the led lights and then mod the ligths to fit so the screw holes for the light casings can remain. So far I think they are looking good. Its not finished yet but here is some teaser shots I took. I will update later. O and since the caseing is still waterproof and the led lights are watterproof in there own right I think I am covered

I ordered the same LED lights a week ago. Can't you just spray paint the casing black while covering the glass portion with some tape? My Wee is black too so I am very interested in the outcome, however I did not plan to invest more into the LED lights.

20$ for the lights form princess auto so its cheap lol. Just need to be good with atleast a dremmel or a mill if you got one. They can be painted but lets face it this way will look cooler and more protection for the light. and as I know they only come in green, Honestlay don't care if they lightup green, I want the metal casing, its a nice one

I am in the process of making some mounting brackets for two of the red waterproof 3W LED's. Going to mount them as running lights/turn signals. These things sure are bright, but the waterproof ones are also very directional. These things, according to the manufacturer, are rated at 14VDC max. Since the charging system outputs more than that at speed, I made a little voltage regulator to make sure they do not see more than about 13VDC. Just something to be aware of. Overdriving LED's is a sure way to fry them.

so whats the max wattage the system puts out then ???? and do you have plans for the regulator ???

It might be overkill or not totally necessary, I dont know, but it gives me peace of mind that they wont see voltages over 12-13VDC. No it is not hard.
All you need is an LM317 and two set resistors. You can find the circuit on the LM317 datasheet. All the info you need is there. Vout = 1.25(1 + R2/R1) + a term you can ignore for this purpose. I used 255 ohm for R1 and 2400 ohm for R2, other combinations are possible. Small 1/4 W resistors are fine. The TO220 package is probably the easiest for this purpose. These regulators are capable of 1.5A current output but a heatsink would be required. These LED's do not draw that much. I'll post a pic when I get home.

did note on there site they start they work for cars, and cars regularly hit 14volts. So to be honest its most likely overkill but still safe then sorry.

I set the LM317 to limit the voltage to 13VDC. At 14.3VDC in, the voltage I see @5000rpm on my battery, the LED sees 13VDC. At 12VDC in, the led sees about
10.5VDC (the tradeoff for the design being simple, but you dont see much difference in output between 10.5 & 13VDC). What is interesting is the fact that these LED's draw max current at less than 12-13VDC.
At 13VDC at the LED, the current draw is 130mA, so about 1.7W, with a mere 0.17W dissipated in the regulator so no heatsink is needed.
At about 7VDC or so the current draw is about 220mA, so about 1.54W.
They turn on at about [email protected]
Again, I do not know if it is 'absolutely' necessary, but it wont hurt anything and it is trivial to do.
