Bulb out... Really?

renesis · 07-18-2012, 09:03 PM

Hi guys!

The bulb warning light just came on in my Z and after looking around about 15 times all my lights are okay even the interior ones...

What's up with that?

The only thing I noticed is that one of my rear reflectors lights up dimmer than the other one (that's weird because it doesn't look like there are two bulbs in there?)

Could that make the bulb warning come on?

Is there a way to turn it off?

How can I change that bulb? It seems very hard to access since it's in the rear fender...

Thanks!

A lot of times a bulb that is almost out will trigger the warning light. I'd keep checking over the next week or so and I'd be surprised if you don't see a bulb out. Short of replacing every bulb, I don't know of another way around this...maybe others will chime in.

Some bulbs are dual element, so the dim bulb may have one element gone.

And that would be enough to trigger a bulb out warning?

Yes, it can. Common culprit for that would be the dual-stage break lights.
