Not positive. Very easy to get to the 3rd brake light bulb. If it was me I'd take the old bulb out and put the new one in right in the parts store parking lot. It only takes 2 screws to take the 3rd brake light off.

I believe he means the cargo lights. Not the clearance lamps.

There was also a thread on here a few months back about the third brake light having an affect on your torque convertor lock/unlock, so dont let it go to long in case your truck is one of those trucks

I've seen cases where the 3rd brake light being out caused a cruise control issue as well.
