Default Running Light Issue

Weird LF driving light problem with my '03. I have replaced both sides in the last year or so with the leds. Sometimes it does not come on with the ignition. Other times it shows a white light? Really? Other times it sits there flashing. These symptoms vary depending on whether the running lights or the headlights are turned on. At one time, I can't remember which side. I replaced it with a standard bulb. That ended up melting some plastic. 😡

Do you have a hyper flash module installed? It regulates the electrical system to make LEDs work with a system designed to use incandescents.

Is this the factory part, or some option?

It's an aftermarket part available from many vendors. Easy to install and cost about $40.
