Slowly going through and replacing mine. The truck had pretty much no lights that worked beside the headlights. Don't know the PO even drove.

This thread is a great idea, I always have to hunt around for the sizes when I want to replace something

Glad it helped.🙂 Actually, you can pull out the stock halogen bulb, generally, there is a bulb size on it.

When I bought my '06 the headlights and brake lights worked and that was it. Dark inside, too. I don't know how a person can live with something like that. I know I can't.

What about the tiny shifter illumination bulb?

Awesome. Was looking for dome

Country of manufacturer of the bulbs?

US or China?

Hi, the tiny shifter illumination bulb is smaller than T10 bulbs(license plate light bulb). It's apity to tell you that we don't the tiny LED bulb for it at the moment.

Thanks for the work here. Am going through replacing bulbs this week.

This is a great thread -- I was just searching for one like it a week or two ago for my 2003

Glad it 's helpful. Looking forward to your pics after completing installation. 🙂

We're glad this thread is useful for you. Will you replace the stock halogen bulbs by yourself? If you run into any problems while installing, feel free to contact us for support. 😊

Not sure about the headlights yet -- I'm more interested in the interior lighting, running boards, etc.

Will there be an 03-05 list/kit available in the future?
