I happened to throw the packaging in the glove box for the marker lights I bought. Its the same part #. . I'll buy another set today, since they're cheap, just to make sure it wasn't those bulbs.

 

1. The front bulbs may be okay if you had already previously replaced them; but, it would be good to check the filaments.

2. From what you mentioned regarding the accessory cigarette lighter add-on, there may be a short in the wiring that is affecting the front turn signal/side markers. -- Try this as a test, unplug under-dash Fuse No. 9 (15A), this is the fuse for the accessory power socket relay. Does the front turn signal/side marker go out with Fuse No. 9 pulled?

If it does, there probably is a short in the wiring, where the exposed power wire for the accessory power socket is touching other exposed wiring.

3. I haven't confirmed whether some of the buttons on the climate control system light up or not, even if you did not have the other issues.
