Do the 05 SD still use 9007 bulbs.

I want to upgrade the lighting on my truck and was wondering if the 05 uses the same bulbs as the earlier models. I was thinking about trying the Piaa Extreme White bulbs.

Nope, different bulbs, I believe they are 9008. The bulbs are actually good and so is the housing.

The problem is the voltage to bulbs is about 11V last I measured. You need to add an upgraded harness to increase voltage to almost 14V. I have done a few of those so far with great results. The Harness is available on our site Link.

You only need the Relay harness, if you want to use your existing plugs. We could supply new plugs as well, they are also listed on the same page, and we will have them pre-wired for you.

If you have any other question, feel free to contact me.
