I have a 2 Door 1999 Chevrolet Tahoe that has a Yukon front grille. I recently bought some new headlights and taillights for it. What bulbs do I need for the front parking lights, side markers, brake lights and backup lights? I have searched online and have been getting mixed answers. For example, I was looking for parking light bulbs for an OBS GMC and one website showed 3157 while another website showed 1157. So, I thought I would just post here instead. I trust the members here more than random websites. I have attached the exact headlights, parking lights and taillights that I purchased. Thanks in advance.

What harness are you using? Does the harness on the truck fit the new lights? If so, you may be able to use the same bulbs as before.
1157 bulbs have a round base with bayonet style sockets. 3157s have flat bases. Two different animals.

As far as I know, the harness has not been changed, so it should be the original one. The new tail lights that I bought already have bulbs included, so I may just use the parking light bulbs that I already have. Thanks for the help.

From a 98 manual, these are what I’ve always used…
I actually downloaded that manual a couple of days ago. Very helpful. Thanks everyone for the help.
