on some cars the tail lights and brake lights are totally different bulbs gain access to the bulbs and have someone push the brakes so that you can determine which bulbs are the brake lights and replace the tail lights
98 sierra1500 4x4 all lights work excepttail lights fuses are good bulbs are new
make sure your bulbs are in the right way(tail light bulbs are polarity sensitve). Just remove the bulbs and twist them in the other way(you can do this with the lights on to check if the bulbs are good). Also, I know this is kinda simple, but check to make sure you plugged them back in (I've done it!)
Sometimes the bulbs have just blown, its not the wires as much as the bulb try replacing them with the spare bulbs in the box. But if thats not good enough then return them and get your money back! Simple as that!
Perhaps something in the gear shift that turns on the lights when in reverse position.
how can i fix lic plate lights not working when bulbs and fuse are good?
It could be the brake light switch (the switch that activates the brake lights when you step on the brake pedal) has gone bad
check fuses, check bulbs, from there see if there is a grond for your reverse lights that may need cleaning. If still no lights, make sure there is a good wire back to the transmission for your lights. Still no luck, look into the sensor on tranny for your reverse lights. Good luck.
It may be a back up switch located on top of transmission.
If the parking/tailight fuse is good - then it may be a bad headlight switch No tail lights but the bulbs are working? Please explain.
if the bulbs are not bad, it is the fuse, if the fuse is good, its the wiring.
check bulbs, fuses & reverse switch
check the ground for the lights
Change front light bulbs
Check dimmer switch.
check if the bulbs are burnt out. If they arent check the fuse to see if it is blown. Sometimes this is rare the fuse is good, the bulbs are good but the actual switch you use to turn the lights on could be bad, its happened to me once before
Make sure that you used the correct bulbs. If you look at the bulbs in the store, you will notice that some bulbs have one element in them and some bulbs have two elements in them. If you bought the bulb with only one element, you won't have break lights - just tail lights. You need the bulb with two elements. Check the book at the auto parts store and make sure that you buy the correct bulbs. I'm having the same problem with my 1991 Honda Accord. I'm not getting any power to the break lights.The one in the back window wont work either. The Tail lights work but the break light wont. Fuse and bulbs are good. Please help.
Answer: Did you check the light bulbs first. Normally bulbs will burn out quicker than a fuse. If the tail light bulbs are good (don't assume they "look" good), then you will need to take a look at a possible lighting relay issue.
The next thing to check is the switch that activates the brake lights. It is probably on the master cylinder.
that points to a broken wire to the light, a bd ground wire or a bad light switch
Check bulbs Check stop light switch Also make sure you have the right bulbs model 2057 bulbs.
Likely to be the brake light switch on the pedal at fault if the bulbs and fuses are good and other lights work ok.
Did you check the bulbs?
did you check the reverse switch on the trans ?
Check the fuses Check the backup switch Check the wiring - make sure that there is good contact.
