my led taillight project.

ok so for the longest time ive had intentions of takig out my taillight and integrating one into my magnum rear compartment. last night while riding with the gang, I got stopped by the police for having a bad taillight. so today i went to my local electronics store and bought a whole buch of leds resistors and random shizz and took the initiative to finally get it the way i want it after 2 years...

the design is supposed to be similar in style to that of a super bike let me know what you guys think.

and then when i tap the brakes. BAM!

right now thats running off a 9 volt battery. hopefully it wont blow when im going down hills. im running these leds in 2 seperate circuits each in paralell and each having a 100 ohm 1/2 watt resistor running in series with each led.

i bought some rectifiers good to 6 amps but i dont know if i run them in series or paralell before the whole circuit. can anyone help me here?

my bike used to have cat eyes but i took em out. im putting them back in and next to the taillights on that same board im putting amber arrows and going to attempt to hide the cateye module in the compartment my oil container used to be.

sorry if my grammar is a bit odd.. its 4:39 in the morning and i just finished soldering..... bahh work is gonna be interesting later

Re: my led taillight project.

Put a voltage regulator on if you're worried about blowing them which I would be.

Re: my led taillight project.

Put the Rectifier between the ground and the LEDs, Run that in Series

Re: my led taillight project.

would i use zener diode as a voltage regulator? thanks for the advice eschuk ill try that

Re: my led taillight project.

I want one!

Re: my led taillight project.

A diode won't regulate voltage, it'll just convert the AC to DC. You need an actual voltage regulator, you could use the one 1977 sells or you could buy a 5V regulator from an electronics place. Make sure it can handle the high current being input (probably like 3 amps).

Re: my led taillight project.

You don't need a regulator if you set the resister so that the current does not exceed the max at max voltage. LED's are quite good at low voltage.

LED's have a reverse voltage problem at about 4 volts. Therefore you need a diode to stop the reverse voltage is you run it off of AC. If you run it off DC, NO PROBLIMO!!!!!!!!!!!!!

Re: my led taillight project.

joe ho put it on your bike by weds!

Re: my led taillight project.

already on. i think a few leds may not be working right now. i dunno. im gonna cut plexiglasss to fitt and maybe tint it so you cant see the circuit board. i also cut my rear fender to be sharp. it didnt look right wrapping all the way around the rear tire with the style that it is. but i didnt wanna take it out completely

Re: my led taillight project.

Nice work Joe!

Re: my led taillight project.

thats awesome man. i want to do that, but im not so good with wiring yet. i might attempt it though.

Re: my led taillight project.

im moving soon and could use all the cash i can get. if you really have your heart set on it i could wire one up for you for some dough. if not in your rear fairing i could make one work for your stock taillight. of course i wouldnt wanna push that on you its just an idea. it takes alot of time but it comes out really nicely

Re: my led taillight project.

i think i might just buy an led taillight and do some "engineering" to get it in the rear fairing. thanks for the offer though man.

Re: my led taillight project.

actually, how much would you want to do this? i would need it completed to an extent where i wouldnt have to do much wiring.

Re: my led taillight project.

maybe 50 plus whatever the parts cost? (PROBABLY 30) i would just bring it down to 3 wires. stop, running and ground.(same as original)
