Rear tailight problem

[BLKWDW]

Hey all i've recently noticed a problem with my right hand tailights on the gq. The brake light works fine the parker light works fine but when you brake whilst the parker light is on the whole globe goes out.
Any reason for this.

Try changing the globe.

I have i swapped the left hand globe over and it done the same thing.

Sounds like you've got a short somewhere, hopefully one of the electrical gurus will help.

You have an earth problem at the right hand side tail light.

Either the socket that the bulb pushes into is corroded or the earth wire that runs to that tail light is broken or has a bad connection.

If you look closely at the bulb when the parks lights are on you will see that both filaments inside the bulb are glowing, when only one should be.

OK, have you got a test light?
If so, get a good earth point and check the centre contacts while someone puts their foot on the brake. If the test light glows you've got an earth problem.
If the test light doesn't glow you need to look why it's not getting power.

No mate when the parkers are on only one filament is glowing and the other one glows when the brake is applied. When the filament is glowing with the parkers on and you press the brakes it goes out and the brake doesnt come on.

No but looks like i'll be getting one. I cant see why it doesnt have power as it works when the parkers arnt on.

Get yourself a length of wire strip back both ends, put one end on the bulb housing (not the pins at the end of the bulb) and the other end connect to something metal, make sure it has a good clean connection.

Now retry your lights.
