My friend and I have been looking for a summer project and he loves working on my bike with me since he can't get his own. I came across the LED Pegs and we decided that it'll be our project. I've been going through all the threads i could find on here, but i still have a couple questions.

What mcd should I use? Sounds like people are saying at least 8000.

What size? Sounds like the LED king Tripage uses 3mm LEDs, so thats what i'll probably try to get unless convinced otherwise. I'm gonna have to get 2 rows facing the back if i'm gonna have turn signals and brake lights on the back.

Whats the best/cheapest place to buy the LEDs?

Will viewing angle really matter that much? I saw one post that said 45-60 should be enough, while some others were going with the widest viewing angle possible.

Based on pics i've seen, i think the 20 per peg facing the rear would work best. Should i wire them all in series, or do 5 in a series and put 4 of those in parallel?

Anything else I should know?

Will this diagram that i've made work? its based off of what i've found here.

I think that setup would be easier to wire than putting red LEDs only on the back and then trying to wire them up so they are brake, turn signals and running lights.

Thanks for the help guys!

Most 3mm LED's I've worked with in the past work on about 3.0-3.5v to run. So you would need to run 4 in series, and 5 sets in parallel so each set gets 12v. You could probably do 5 series 4 parallel as you said. Depends on the voltage the LED runs on. And remember the higher the voltage, the brighter the light, but also the shorter life span and likely hood they burn out.


As for your diagram. The bottom one with side running lights/turn signals, dual color LED's come with 3 leads, one negative and a positive for each color.
As for the top left one, if you want to run running lights and brake lights I haven't tested but am pretty sure they are both 12v. I would try using a resistor on the running lights to lower the voltage going to the LED's. That way when you use brakes the voltage goes up and they get brighter. Just remember too low of voltage, aka too much resistance, the LED's won't turn on.

You should be able to use a amber/red LED and and split the lead for 12v Red like the image on the top left. You would have running lights, brake, and turn signals in 1 LED.

And not really sure what you were getting at on the top right diagram.

As for viewing angle. I think even 30 would be fine, if someone is at greater then a 30 degree angle from you your front signals, assuming they're aftermarkets, will be visible from the side. 45 would probably work good.

And in the past I have ordered LED's from oznium.com and digikey.com
If you spend the time in the catalog digikey has an enormous selection, and I'm not too sure oznium has dual colored LED's. Been a while since I looked.

Hope this helped.

how long of a lifespan should i expect?

I'm going to have 3 lines of LEDs. One set of orange facing the side (bottom left), and 2 sets facing the back, one orange and one red. (top two). So i wouldn't need dual color LEDs (plus i assume those would be more expensive) and its part of the reason 3mm leds are needed, so i can fit both lines on the rear facing side of the pegs.

Someone else i showed the diagram to mentioned the resistor and said i should use a 1/2 watt resistor on the running light.

As for viewing angle. I think even 30 would be fine, if someone is at greater then a 30 degree angle from you your front signals, assuming they're aftermarkets, will be visible from the side. 45 would probably work good.

I just put on some protons.

i'll check them out

thanks for the input!

so i decided on 10,000 mcd amber leds and 15,000 mcd red leds that i found on ebay.

Dunno on lifespan, if you run it at the higher voltage they say they run, theyll prolly still outlive the bike. Goodluck
