Lights going out because of LEDs ???

[Bjmillion]

I have a 21 bighorn I got some led bulbs for Christmas I installed them and everything has been fun until this week now one of the low beam headlights don’t work as well as one brake and running light and a rear blinker as well. All bulbs are good it’s an electrical issue has anyone dealt with this issue? Thank you.

That is PWM at work. The lights are controlled with Pulse Width Modulation, LED's don't like that. The best way is to get AlfaOBD and change the settings for your lights. They should al be set to LED, so the PWM is turned off.

Cheap LEDs cause that. I swapped all my bulbs to leds and have had zero issues.

Agree with the cheap LED bulb comment. What brand of bulbs are they?

Is it pretty easy to do ? So once it’s switched off my lights will work again? I know I’m going to get pulled over for having lights out.
