| Incorrect Bulb Specification in Owner's Manual
Not a big deal unless you think you're carrying the correct spare bulbs based on information in owners manual. On my '07--yours may differ--manual states rear brake/tail lights are double-filament bulbs, i.e. 21/4 watts. (Two per side, BTW.) Investigation shows they are single-filament bulbs--21 watt--and the car's electrical system apparently runs them at lower voltage when in tail light mode and increases voltage to obtain full brightness when brake pedal depressed. 21/4 watt (double-filament) bulbs in all liklihooed will not operate from these sockets. |
