    Hello everyone.
    Bought a rear LED light. Really happy with the design but the light output is weak (brake and signal lights are ok). It is so weak that people think I'm driving without lights.
    Is there any way I can upgrade the current LED output?
    Thanks

    Not easily. Either a resistor has to be changed internally, or you can up the voltage going to them. Neither option is really a great solution.

    I understand that increasing voltage might cause overheat and LED failure.
    What the issue with replacing the resistor? how can it solve the problem and why it is not a great solution?

    When you say, "rear LED light," are you referring to a pair of LED tail lights?

    Changing the resistor does the same thing as far as operating voltage. The resistors I’m referring to are in series with the actual LEDs, so they reduce the voltage by a percent. So if your truck is sending 12V to the parking lights, the resistor might be reducing that by 33%, so the LEDs only receive 8V. So let’s say you want the LEDs to receive 10V, you either swap the resistor to one that reduces the voltage by 17%, or you increase the voltage to 15V. They would be soldered into the LED board anyway, so would require disassembling the lights. And if you are going that far, you would probably be better swapping the actual LEDs themselves.

    TLDR: Not really any good options, sorry.

    I see. No good options. not going to risk burning the truck just to get brighter LEDs.
    Thanks for the info.

    yea i would check which lights are are talking about. did you buy new tail lights? are they tinted by any chance? if so pick up non tinted and you should be good.
