  • Led Corner Light Retrofit (Zenki)

    I have been wanting to do some thing with leds for a while now so i finally bit the bullet and ordered some leds along with new corner lamps. Im using Cree P4 amber leds.
    I <3 Nissan boxes



    Breadboard testing:




    Just for craps and laughs I free soldered the 12v regulator, complete with caps and diodes



    First prototype, i will be going down to 50ma instead of 70ma:







    More to come soon when i have plans set in stone. Regulators will be external, in case i want to pwm later down the road and so i can have heatsink out of the lamp.
    Thanks,
    Nick

    Well i have done a little more, little by little I'm coming along. I pulled the leds down to 50ma and 132 of them are bright enough. I finished the above prototype and then started making new boards then painted them silver and solder up some leds.
    Lay them out:

    Solder them into place:


    Run the ground wires:

    Then run the resistors:

    Final product:




    Now i get to make another one

        wowza, that's a lot of LEDs for that.... why so bright? It's facing the side.... now if it were facing forward, I could understand. I need to build some of these for my head lights!

          How many lumen does each LED output?

            @ Gold94carolla: They really dont face the side as much as you may think, but yes a lot of it faces the sides. I was planning for full coverage. This is also my first time with something like this so idk what i was really doing. I didn't plan for them to be that bright, i even ran them down 20ma so they would be less bright. But i also wanted an even coverage from within the light, so it didn't appear spotted.

            @Sean Lezner: Each led will put out 8.730 lumens @70ma, I'm how ever running them at 50ma so each one is probably putting out 6.6 lumens. And 6.6 x 264 = 1,742.4 lumens, which is 871 lumens per light. Is my math right??? 1700 lumens created by just under 4 watts is good i think.

            Any who I finished them up today and i will enjoy putting them into my car and driving at night

                  Well if you don't have fog lights now, just turn on your park lights haha. Nice work! I love how crammed that regulator looks and painting the circuit board was a good idea.

                    Any pics of it off?

                      Yeah that regulator will not be used like that they don't look that bad when off, but it's almost not even noticeable when off, and only the people that know about retrofitting will notice it

                        ^^^ It would be nice if that lens was clear and not fluted.

                          I disagree, I really like flouted lenses with LEDs! Makes for a stealth install and you don't have to care much about what the LED board looks like.

                          Yeah no one will notice that back there. I'd have painted some more of the back of it chrome, you can see the back and resistors.

                          But you should definitely put a PWM on this so that it also functions as a turn signal!

                            Give me a sweet deal on some CBIs and ill see what i can do

                            @G94C They arent sealed up yet so i think i might mask off the lights and paint the underside where it is visible. I also have two bumper lights for blinkers so i might not pwm the drls and just retro some leds in the bumper lights.

                              The corner lights shine more to the sides, whereas the bumper lights are forward only. It doesn't hurt to have better side visibility on the signal.
