torcy27 Posted October 26, 2022 Share Posted October 26, 2022 (edited) Is there an alternative led lamp version of this that dims when going on a straight line. H11 lamps are fitted. Edited October 26, 2022 by torcy27 Quote Link to comment Share on other sites More sharing options...

H11 lamps are fitted. Finding LEDs that will dim is unlikely. The halogens dim by pulse width modulation. This does not work with LEDs unless there is a special module to convert PWM to diminished current to the LED. But maybe you can find something on Amazon or other site. Make sure it can convert PWM signals. Good luck. If you didn't know, PWM turns the power on/off at different rates to cause the incandescent bulb to not fully light. LEDs light instantly so the pulses cause the LEDs to flash. You dim an LED by lowering the current flowing through it, not the voltage. These current limiting circuits are more complicated than simple voltage reduction or PWM. Quote Link to comment Share on other sites More sharing options...

No. There is nothing developed for the automotive aftermarket. You can try to engineer a solution by way of LED drivers and a potentiometer. I would not recommend trying.
