Rear blinker problems

[kook911]

Ok now on to the next problem. On my rear brakes the top bulbs on each side are out. I went out and got the 2057 bulbs. Plugged the bulbs in and was getting the real fast blinking. Took them out and went back to normal. I then placed the blub into the socket the incorrect way (where it will not lock into place) and when I push down, the blinker will blink normally. So did I somehow buy the wrong bulbs?

Yeah they're the correct bulbs.

Make sure the ground is in good shape, it's behind the driver's side tail light. Can't hurt to check the connector got the tail light harness, either, along the driver's side frame between the rear wheel and bumper. Make sure you've got the correct bulbs working properly up front as well.

Package says I got the correct blub. Also drill out the hole for the ground and got it to bare metal. Put a larger bolt with nut just to make sure. Check everything and all looks good. I'm going to pick up a pack local to me and see. The last set I bought off rock auto so it might be the wrong blub in the correct package.

I would still call it unlikely that the bulb is wrong. There's a chance it got damaged in shipping but if anything it would just be broken or burnt out. Should be a two-filament deal, as long as that's the case I doubt it'll cause problems. Does the light illuminate with the fast/regular blinking?

Another thing you can do is swap the hazard light flasher with the turn signal flasher. Two cylindrical relays in your fuse block.

 

Your flasher will flash quickly if it doesn't have enough load on it (like if a bulb is burnt out) or if there's power coming around it (from some other source... one of our work trucks does this because the lights on the service body were wired into both brake and turn signals, so if you step on the brakes the signals speed up).

So if you're getting fast blinking all the time, in both directions, either there's a bulb out somewhere or there 12v shorting somewhere, or you've got an open circuit.

Do all four of the front bulbs work? Do your hazard lights work? Does anything change if you've got your parking lights or headlights on?

One other thing. Do you have trailer wires? If so, what does the connection point look like? If you don't need them and they're as sketchy as most of them are at this age, might as well just get rid of them.

I spent 2 months replacing bulbs in my rig with the right side blinker not working correctly. The final solution, I replaced all the bulbs ( left & ride sides) with the same company bulbs. It seems the replacement bulbs I bought at the parts store were of a different company. ( I will assume the load ( impedance) is slightly different & caused me all kinds of problems. When all the bulbs were from the same manufacturer, the problem was eliminated.

 

Of course, I had already cleaned all the bulbs sockets, cut of the end of the ground wire and installed a new end, cleaned the metal and reinstalled the ground, replaced the fuses and added a second ground wire on the driver side. 

 

Just another minor problem and repair that took me around the barn the fix!
