This is a brand new front turn signal and parking light assembly for the driver side (left front) of your 1998 through 2002 Pontiac Trans Am.
Made by UpParts, it's a direct replacement for the factory unit – part number 10301405, which also crosses over to GM2520177 and 116-03448L.

The lens is clear (not amber), which gives it that clean modern look, but the bulb inside lights up amber when signaling.
It uses halogen lighting technology – bright and reliable, but bulbs are not included, so you'll need to grab a pair separately or reuse your old ones if they still work.

Mounts in the front left corner of the bumper, and it's a direct bolt-on replacement – no modifications needed.
Just unbolt the old one, plug in the wiring harness, and bolt the new one in.

Perfect for Trans Am owners who want to freshen up the front end.
If you're doing both sides, grab the passenger side separately.
