License Plate Lights

Possibly. I'll find out.

 

With regards to Fluorescent:

 

GE, Bucyrus, Ohio
GE, Circleville, Ohio
GE, Logan, Ohio (makes glass tubes for above plants)

Ledvance, (Formally Sylvania) Versailles, KY

Philips, Salina, KS

Interlectric, Warren, PA

Of the above, currently only Circleville, Ohio lamp plant is slated for closure later in 2017. Bucyrus now makes some LED retrofit tubes.

The only downside to swapping in LED bulbs in the license plate lamps is that OnStar constantly sends you bulb out warnings. Has anyone figured out a way to stop that?

Yes you are correct, got my first e-mail yesterday evening and said WTH is this crap, checked every light on the truck last night and went about my happy way.
