My tail light does not work on my right side and I cahanged the bulb in it and now just the blinker and the brake light works do hav a solution for my problem. Its in a 1998 ford expedition.

So your taillights should have 2 bulbs in them. 1 that turns on when you turn your lights on and stays on until you turn them off. That same bulb should have a 2nd circuit that lights up when you press on your brakes. The 2nd bulb appears when your reverse gear is engaged. So if you have no lights on right you have to replace both bulbs and if you have no brake light on the left you just have to replace your rear brake light bulb.

I would recommend taking out the tail light. Get a test light, have an assantant step on brake. U will see the bulb in tailamp light up. Probe the wire w/your test lamp. That is brake wire. Repeat that process for blinker.. Drop down those two wires. Hook that to the same side on trailor. Repeat for left and you should be all set.

Start by replacing the light bulb.

most blinkers uses relays, and when they flashes fast one light is out, but you replaced your burnt bulb might be a bad relay.

Your right rear turn signal bulb is blown.Replace the bulb and the fast blinking will stop.

You have a bad/wrong bulb installed somewhere.

most likely a bad ground in your electrical system; consult your local mechanic

TEST FRONT RIGHT BLINKER CIRCUIT AND REPLACE THE BULB,,WITH PROPER BULB...A DOUBLE CIRCUIT BULB IN A SINGLE SOCKET WILL DO THAT ALSO A SINGLE SOCKET BULB IN A DOUBLE SOCKET HOLDER....CHECK LEFT SIDE BULB FOR ACURANCY

try running your own earth wire to your pigs tail---WOW AMERICAN ,iam getting their

If the driver's side tail light is working, it's not a fuse. Use a test light to check for power at the bulb holder. One terminal will be for tail light, the other for brake/turn light. If the is constant power for tail light, replace bulb. If no power, trace wiring from bulb holder to driver's side junction. Probable broken wire between the two tail lights.
