You have a turn signal light-bulb out .
Sounds like the turn signal indicator lights.Sounds like the turn signal indicator lights.
If you are getting an indicator of a burned out light, but don't see a burned out light, it must be a turn signal light. On a Mercedes, you'll actually get a "burned out light" indicator if the turn signal is not working.
change it from the inside
You change them from the INSIDE.
It means that the light is about to go out. For example if you turn on your right blinker and it is blinking fast it means the light is about to go out and you should change it.
These symptoms indicate that there is either:a failure of the signal light switcha bad ground in the signal and head light circuits.
I'll make this easy for you... 1) Remove old bulb 2) Instert new bulb 3) ?????????? 4) Profit!!
What indicator are you talking about? Turn signal, emergency flasher, check engine light, abs light, oil light, temp light, alt light, etc. We can't read your mind.
A turn signal indicator can be replaced by first removing the burnt out light inside of the glass chassis. The new bulb will then be installed in the same fashion.
my rear left indicator and alarm light doesnt work, hoe do I change the bulb?.
There is a relay switch in the circuit which switches the light on & off when you activate the turn signal.
