    I'm having the same problem with my 2006 H3 and I've changed the bulb. I took the bulb out and put it in the left side to confirm the bulb is good & both the new one I just put in AND the old one I thought was no good lit. I put the one I took out of the left side (also confirmed good) but that didn't work either. The brake and reverse lights are working and the front right signal light blinks but much more quickly which is why I was sure it was just a blown bulb (# 3157). One thing I did notice is the actual socket almost looks slightly burned right around the opening where the bulb is inserted so I don't know if I should replace the actual socket or if anyone has any other suggestions. I also checked all the fuses but didn't replace them because they looked fine. I'll probably replace them anyway to be sure but any other suggestions would be appreciated?

I have sourced out all fuses and bulbs, yet continue to have a rapid right turn signal. I don't know where else to look. help?

replace the right rear bulb. the quick flashing indicates a bad bulb. it could be a wiring problem to the rear for the signal light that you will have to check out starting at the socket and working forward.

My right turn signal flashes rapidly, and after turning it suppose to turn off itself but i have to turn off the signal manually. the left sometimes turn off itself.. how can i fix this? 98 buick century

when signal is rapid it useually means that a light is out. About your signal not turning it self off.
That is a defective indicator switch which useually means removal of steering wheel.

The rapid flashing occurs because of the light problem. If the 20A PARK LP fuse in the underhood fuse block is OK, the front marker lamps and the park lights should turn on when you set the headlamp switch to PARK. If the 10A T/SIG fuse in the instrument panel fuse block is OK, and the ignition switch is on, moving the turn signal multi-function switch to signal a right or left turn should cause the turn signals to flash. If this doesn't happen, check for a missing ground connection to the socket you replaced and check to be sure the replacement lamp was not forced into the socket backwards (it happens).

My name is Dave, any help would be much appreciated! When I turn on the left or right directional indicator from the lever on the steering column it makes a rapid blinking on the control panel, the front...

Hi, I have a couple of questions.
1. were the signals working before you replaced the brake light bulbs, and did you use the recommended bulbs?
2. Do the brake lights work now?

The brakes and signals use the same filaments, so these things are tied together.

2005 Lincoln Town Car - Right turn signal is rapid blinking. ALL bulbs and front and rear have been replaced. It is still rapid blinking only on the right side. Is there a fuse that needs to be replaced?...

You might check the courtesy cornering lights that illuminate and do not blink. These go on to shine on the front corners of the car. Since they use electric when the blinkers work, it may make the blinkers work faster if the cornering bulb is burned out. You probably are not noticing that the cornering light is not on.

I wanted to know if the flasher can knock out the right side flasher lights while the left side is working but flashing very fast?

Fast flashing occurs when one or more signal lights burn out on that side--front or rear. Other than the stress of turning the lamps off and on, the flasher should not cause rapid burn-out of any lamps. If any lamp doesn't work even with a new bulb, check for a poor grounding connection locally.

Blinker lights are rapid

I assumer you're getting a a "check left turn signal" error message too? The rapid flash is the car's way of letting you know you've got a bulb out. The front bulbs can be tricky since they're double filament. If one filament is out the light may look dim. Set the hazards on and inspect. Last time this happened to me on my 2001 S60, the bulb was fine and the socket was flaky. You may need to clean the contacts and check the resistance from the plug to the socket. Mine is working now - for the time being. I hope it's not your front bulb because you have to remove the air filter to get to it. Good luck!
