Vauxhall Astra - Cannot Flash Headlights

Most likely it's the switch.

Seconnded, I had same thing. Turned out to be the switch £23 iirc.

But first check the multi-plugs on the back of the bulbs i had one that had all melted on the inside, caused all sorts of headlamp related mayhem.

Tom

its on the other end of the lever you use to flash the lights. :)

Really?

It's the thing you use to try to flash the lights.

Si

why do you want to flash your lights anyway ?

I don't.

Tom Burton ( snipped-for-privacy@freezingcoldmail.com) gurgled happily, sounding much like they were saying :

Which bit of "Main beam works fine" did you miss...?

I wasn't asking you :)

He was being pedantic, as you replied to his post asking him...

He knew that. You don't get away with poor attributions in UKRM y'know :)

When you have the headlights on and "flash" it simply illuminates the main beam filament, in addition to the "dipped" (if switched on) - or it does on my car - though I seem to recall it being different on other cars?

Assuming the Dipped Headlamps are on, when one switches the main beam on 'permanent -I.e. not momentary it cuts the supply to the dipped filament, presumably to stop the lamp overheating.

When the multi plug melted and corroded on my lamp, strange things such as the dip filament would stay illuminated, sometimes fully sometimes not with the main beam on, sometimes it would illuminate the wrong filament on flash etc or another favourite was the main beam would illuminate turning left and extinguish when going right. Symptoms pretty much depended on the day of the week.- hence 'headlamp related mayhem'.

For the sake of 20 seconds looking under the bonnet its worth a look.

Was he ?
