Default Rear Signal Lights

So tonight we were driving home and we noticed when we turned on the blinkers either to the left side or right it would blink really fast inside the car. I get home and noticed both signal lights in the front work and blink rapidly but the rears dont.. any ideas on where to start diagnosing?

the imbalance of the rears not working is sending all the power to the front blinkers which makes it blink rapidly. i'm not knowledgeable enough to tell you where to start looking LOL connections for your rear taillights? what did you mess with last before you realized the blinkers were like that? check the bulbs and ensure they are secured tightly in the connector.. when i had my IS that happend to me when i changed out my front turn signal bulbs to chrome amber bulbs. since they were aftermarket they had to be forced in the connector to secure.

even 1 out of four (two on each headlight) was out in the front and it made my rear signals blink rapidly **** one left bulb up front caused the left signal ONLY to blink rapidly. the right side was blinking normally.

hope that helpss

bulbs are brand new. i just did the 06+ tail light conversion 2 weeks ago.. puzzled now.. i really dont want to tear everything apart again.. it shouldnt be the tail lights because the brakelights and normal lights work with headlights on.

very odd. i'd check the rear bulbs if they are secured properly. its only one screw to take off the taillight :P

hopefully nothing shorted out your rear turn signals bulbs?

One or 2 of the rear bulbs is/are busted. The only thing that will make it do it.

The LED tail-brake lights are not tied with the signals.

Has to be the signal bulbs. Pull the tail and check the bulbs. No need to tear anything apart yet.

When you did your upgrade, did you use LED bulbs for the turn signal indicators?
Blinkers are in a regulated circuit by a type A circuit breaker, using heat and magnetic induction to open and close the circuit rapidly. Properly sized bulbs and voltage rates should be used evenly among the components (light bulbs, resistors, outputs and so on)

The problem could be is a short to ground through an open wire causing a current increase due to less resistance at an accelerated pace since its passing more current. Or a bad bulb.

First thing I'd do is go to sylvania dot com (http://www.sylvania.com/ConsumerProd...lacementGuide/) and see what bulb is suppose to be used.

If everything bulb wise is copasetic, then it time to break out the volt ohm meter and do some circuit testing.

I found the issue. I didn't know that the rear signal bulbs were suppose to snap into to the socket. I snapped it in to socket and issue resolved.

Thanks for the help guys!
