Break Light Switch?

[Scope]

Hi guys,

 

My Galaxy has been running fine for a while, but today it developed symptoms similar to that others have described when their Break Light Switch needed changing:

 

Glow Plug light flashing

 

When headlights is on:

Break Lights constantly on (no change when you press the breaks)

 

When headlights turned to off:

Break lights operate as they should

 

Could this still be the Break Light Switch? (Considering it works fine when the headlights are off?)

 

(I tried to lay on the back next to the break hoping to see something looking like a switch, but couldnt for the life of me see anything looking anything like the break light switch. lol)

 

Im driving a MK2 (2003) 1.9 diesel.

Think its more likely you have shorted wires in the tailgate rubber gaitor(s). Shorts between tail/brake light circuits that is.

I could add that the break light stopped working all together last week, so I replaced the bulb.. I havent driven the car since then I think, so it well have happened then.

In that case, and it has happened before.....you put the wrong bulb type in or put it in incorrectly...so shorting out parking and brake light circuits. That will trigger the glow plug warning. Someone on the forum did the very same thing....

 

The brake light bulb is a type 380 - 21/5W twin filament and should have two connector "blobs" on the base and offset location pins, not symmetrical.

 

NOTE: SOME AUTO BULB SELECTORS (e.g autobulbs direct) SHOW THE INCORRECT BRAKE BULB (single filament) FOR THE SHALAXY,

You were spot on Seatkid. :unsure: Halfords had incorrectly sold me a 382, 21/12w bulb.. I checked their charts myself first, picked the bulb and asked one of the staff to double check I had the right bulb.. I have now removed the bulb and everything seems to be working fine again.. I will be going to Halfords at the weekend to get the bulbs changed - even though I havent got the receipt any more.

 

As always this forum has proven extremely helpful. :unsure:

 

Thanks for all the replies.
