Hey guys, I took out my rear tail lights and was checking for burned out bulbs when my neighbour and I could not figure out what two of the bulbs do.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hey guys, I took out my rear tail lights and was checking for burned out bulbs when my neighbour and I could not figure out what two of the bulbs do. Two of them would not light up for the life of us.... they did not look burned out either (PASSENGER REAR). The bulbs were on the bottom (row with 4 lights)... can someone identify what each of the bulbs do and bulb replacement size.
Thanks
Probably the rear fog light.
Pull the Light switch out two notches (all the way), should only come on only on the left, some people put a bulb on the other side as a spare, but it's not connected to anything.
Yes that is one of the bulbs.... however the right side has 4 bulbs on the bottom and one is the turning light, one I the brake light, but I have no idea what the other two are...
I Just replaced all my rear lights:

Not to resurrect an ancient thread, but I'm having trouble marrying up the bulb numbers/types (that @algiorda posted) with the pic from the manual (that @rick3000 posted).
The 7507's I find online all appear to be amber bulbs. I don't see any amber bulbs on the rear of my car.
I'm a little confused on the bulb types because the manual has a different name/number than what you'd find from Sylvania for example (P21W versus 7506 i think?).
Can someone square me a way on marrying up the pic letters with the bulb type that's needed for each?
If you follow this link you can cross reference what bulbs you need.
Or just buy LED and be done.
Cheers!
