Question on led bulbs

[MOOG5050]

So I just installed sv4 led bulbs from headlight revolution in place of my headlight halogen bulbs. The kit came with a pwm module but it doesn’t fit in the enclosed light. I also swapped my fogs for oracle leds. They did not have a pwm. Both have some sort of module in the harness that connects to the lights. Not sure what that is.

I tried all the lights without the pwm and they seem to be just fine. No flicker etc. Do I need the pwm? Tried calling HR but after waiting on hold 20 min, I gave up. Lol. For what it’s worth, 2023 JLUXR

Probably an anti-flicker module.

You pretty much answered your own question. If they don't flicker, you shouldn't need the PWM.

Thanks Dave. Not sure why the extra $55 pwm was included in the package when you buy the headlight bulbs.

Some vehicles need them, some don't. Don't toss them yet.

How is the quality of [terrestrial] radio station reception when the new LED headlight bulbs are turned on? Same as before, or now worse?

No idea. Just installed them. Will let you know.
