Xenon corning lights question?

Does anybody know if the corning lights has a separate fuse?
My left is not working after I upgraded to led but accidentally flip the light and it turned on but just flickered and now my left is not work just my right.
I thought the light was toast I swapped leds right to left and still same left stop working right works.

​​​​​​Might popped a fuse or something

One Thing To Another... NO LITE!

You upgraded a front bulb to a bright LED and now it just won't turn on...

The lights are electronically controlled and monitored by individual modules. Usually the bulb current must fall within a min/max range.

There are multiple ways to deal with this. I am not sure which can provide the necessary reliability.
This LED upgrade has been done countless times.

Experiment reprogramming the range with a scanner or adding a 20W-hot resistor to dissipate power the normal bulb was consuming.


The bottom line is you want to find a trusted way for your headlights to never quit. Stock does that well.

Sounds like the same problem as with my lights in trunk. Can use only one LED bulb. Two will kot work. Have one new LED and one old fashioned bulb.

This must be some sort of voltage control to the lights...?

Steering wheel module controls cornering lights with wheel position, turn wheel to left, turn on lights and see if there's power to the bulb connector.

Cornering light also works from blinker without turning the wheel...

It was working with the regular bulb. But I think I twisted the wires to much probably came loose off the connector. Going to check it out tomorrow since it's my day off
