I have been getting this "Headlight Tail Light" warning whenever I turn on the lights. Intermitently I keep getting the warning. I checked all bulbs on my headlight and taillights including 3rd brakelight and rear fog light and all is working fine. Any ideas mates? TIA

check the wires on the sockets, there is a read wire for the display reads bulb and if dirty or the bulb is not fitting right will come up on display.

Rusty / samesame is talking absolute rubbish again...

there are no extra wires, it is all resistance measurement based.

Check and replace bulbs in turn with a good brand bulb, often these alerts get triggered when some cheaper bulbs get older.

Also check numberplate bulbs they *may* be checked cant remember.

Please do expand on how a 'wire' can read a simple brake light bulb  :-?

As Jimbob says its resistance based, eBay cheapo bulbs often give a false reading. Bulbs from a Vx dealer are not too bad, might as well get them from a dealer 

Also remember once you replaced the bulbs, you need to press the brake pedal for the check to clear

Different info message, Mate... "Brakelight check" comes on every time the ignition is turned on.
Headlight/tail light refers to the headlights and side lights, nothing to do with brake lights...

Check that you have four red lights, lit up at the back of the car when side lights are on...

Yup, i understand that..... but, 'Headlight Tail/Light' its part of check control, when thats lit, (when a bulb blows) when the replacement is fitted, you need to press brake pedal for check control to sort it self out.

Also Headlight Tail Light does have something to do with rear lights, clue is in the word, Tail 

Same with brake pad sensors, when they fail and its replaced, still pops up when you first turn ignition on, quick press of pedal and fault clears

As Brikhead says .. check for FOUR lights at the back !!!  With this message, many people check the lights with the boot open while they "fiddle" with the rear wing light clusters .. so never seeing the "non-working" lights in the boot !!

A slightly dirty contact/loose bulb can cause the problem as the resistance is then high and the "system" thinks it is open circuit = bulb blown.

black and yellow wire is for display. check volts into light an if no signal comes up saying check it.

Not quite what you said earlier, there are only the feed wires to power the light, and its done on resistance there is no cable for the display

Thanks for all you comments. Does this mean that I have to clean all bulb sockets o do I do a hit-or-miss thing by replacing bulbs one or two at a time?

I'd pop some GM bulbs in and go from there 

[Entwood]

Its usually only one bulb .. so replace a single bulb in turn with a new one... one bulb new in, if the fault remains use the bulb in your hand in the next one .. and so on until the faulty bulb is replaced ..

[Brikhead]

I said it's nothing to do with brake lights, not rear lights. Obviously you have side lights at the rear of the car, or tail lights if you'd prefer...

Best advice IMO. Having had this on my old 2.5 with a warning popping up and a car full of perfectly working lights. It was eventually traced to halfords bulbs not seating in the sockets correctly and also with very soft solder on the bulb pips, or what ever they're called, meaning the spring connector in the bulb socket centre wasn't firm enough connection, hit a bump, the connection is momentarily broken, screech to a halt get out run round the car....nothing all working. Until one day tail light not working, take the bulb out, perfectly complete filaments, put it back in, working again. Closer inspection reveals very tight fit in the light bulb socket, and very worn solder lead/solder pip things on the bulb.

Halfords bulbs mate, shite IMO. Get your bulbs from GM.

Remember, what ever the cause, it's only got to see a break in the circuit, that's all. The connection can be re made after, by accident, does not come into it, all it monitors is the completed circuit, nothing more.

Hth


Also, worth mentioning, take little notice of what "same ip number as rustym95" says, means well I think but unfortunately has confused far too many threads on here to be considered helpful. Sorry Rusty, but we spoke about this before, remember?

You may have one starting to fail. 
A good tap in the dark may make one flicker - otherwise, short of replacing them you might have to wait for it fail properly.

My old 'un gave this a few times before I lost a sidelight - then after driving around for bit (was front - didn't use them) all the messages went away !!!  Hasten to add, did change it later.

Also had this on a txe renault many years ago, talking box kept rabbitting on about the bulb failure (no mute) IIRC it even said which one!  Nothing wrong - change bulb anyway and all okay ever after.  Lovely car - but I had some personal issues with the nice lady in the box.
