Question
Hi
I am living in the UK. Yes, you are correct, I mean high beam. In the UK, we refer to them as full and dipped beam. The high beam is permanantly on at all times and I cannot switch between high and low beam. When I use the car during the day, I have to disable the lights by removing the connection behind the back of each front light assembly. In the UK, we do not have option known as DRP. The rear lights do not come on and the indicators are still working fine.

Hi
I have just bought a 1997 Lantra 1.6GLS Sedan and the full headlight beam is now permenantly on. I have checked all the fuses down by the accelerator pedal and they all seem fine..
I have temporarily isolated the problem by disconnecting the headlight wiring but can only now drive the car during daylight hours.
All other lights are working OK. A friend suggested that some relay switch in the sterring column housing has burnt out...
Any assistance or advice would be greatly appreciated

Hi, Bill. I take it that since you refer to your car as a "Lantra," you're not in the U.S., so I'll presume you have daytime running lamps (DRL).

When you say the "full headlight beam," do you mean what we commonly refer to as "high beams" in the U.S., or do you mean that the low beams are on instead of the DRL?

Answer
Okay, gotcha.  

If it's causing the full beam to stay on, then it's likely the headlamp switch is shorted.  

If you want to do some diagnosis rather than just taking a guess, I'd recommend getting a free account at www.hmaservice.com (requires Internet Explorer and Adobe SVG viewer, a free download).  Once you have an account, you can look at the schematics.  Keep in mind that the site is for U.S. models only, so some schematics will be different than what you have on your vehicle.  But since you don't have DRL, I expect the lighting schematics should be identical or at least similar.

After the switch, the possibilities become less likely.  You'd need to have more than one wire shorted for the full beams to be on and not be able to switch to dipped.  But, since this car is new to you, it's also difficult to know the history.  I've seen odd problems because the vehicle was wrecked and the repair facility wired the fuse box wrong.  It's possible you could have this type of problem.
