Headlamp Switching Off

Brian Gow · February 12, 2012

I was wondering if anyone could offers advice on a strange problem I am having on my IS 250 SEL. Quite frequently the N/S headlight goes out but on every occasion I simply switch all lights off then on again and it works!

I have tried to associate it with heavy bumps in the road etc. but there doesn't appear to be any reason for it going out.

Any advice would be welcomed.

Hello and welcome to the LOC.

You don't mention the year of you IS250 but if you have HID lights there have been cases of the bulbs failing in this way.

The bulbs are expensive from Lexus but there are some good aftermarket suppliers.

If you do replace the bulb change them both as the light output and colour temperature may be slightly different from the originals.

There could of course be a loose connection but odds are on the bulb itself.

I had the same problem with my IS turned out to be the ballest needed changing which Lexus did under warranty. The cost for a new one from Lexus is around £180

There was a similar thread some months back - quite a few people have encountered this problem. On my IS220 I had the ballast and bulb changed (not cheap!) to resolve the problem.

Thanks to everyone for the feedback. I feel a visit to Lexus coming on.

If your are covered under warranty just bring your own chair!
