  • Bi-led retrofit heat question

    I plan to install a Bi-led projector that is all one unit (like Koito, driver integrated with projector). I also plan to install led halo which also has a driver and an inline capacitor due to PWM from car and need constant power. Can I install all these items in the headlight housing and seal it up if they fit or will the heat produced by the heatsink on the projector plus the halo driver and possibly from the capacitor possibly damage the headlight or the devices?

    Will it damage the headlight? Absolutely not. But I would absolutely mount the drivers and caps outside the headlight. They tend to fail and you want them accessible.

      any high heat device is better mounted away from the housing, so it can both get rid of the heat, and also not affect the other components as much. but i don't believe you need to route the kioto driver away from the projector, as that would require a lot of work with no benefit-- those drivers don't make any heat compared to the led they drive.

      but the capacitor/load resistor setup for the pwm correction likely does, and that is the component i would keep away from the led ring and projector.

        I had wanted to just mount everything inside the headlight to keep it clean and easy but I do see the point regarding equipment failure and ease of access. Dont want to have to cut open headlight again unless the projector fails, the other stuff is just swap in/out. Also, checked with distributor and they also recommend putting led driver and the capacitor on the outside for ease of replacement if they fail. Just gotta figure out how to mount the outside the housing.

            Well had some issues with the install and ended up with installing just the projectors and led bulbs in corners so everything is inside the headlight and closed up. There are no additional capacitors or resistors so not concerned with heat. The dust caps are back on but there is a gap underneath the fan of the projector and the housing so hot air vents rights out. Overall a success but disappointed I couldnt get the halos/demon eyes to work. I think it needs a separate relay harness for the mods which I didnt want to do so am happy with final product.
