Hi all. Having an odd problem with my 98 Tacoma. Left taillight is not coming on when headlights are on, but the brake (uses the same bulb) works fine. I've tried cleaning contacts and different (old but unused) bulbs with no change.
Not sure where to start looking. All lights and turn signals work fine other than that single taillight. :confused:

Thanks for any suggestions...

Problem solved. The 2 old but unused 1157 bulbs in my stock (Wagners) may have been the culprits. An old but unused different brand bulb (Eiko) fixed the problem.
