The Depo ones are pretty rudimentary, and the units themselves took some fettling to get the ballasts etc to fit.

A quarter of the price of GM ones though.

Yes, they were really cheap, less than £100 the pair, freight included.

From what I understand, different adjuster motors are used for the xenon and the halogen headlights.
My thought is that a previous owner might have fitted new adjuster motors of the wrong type (ie for headlamps with halogen lamps) and that the stroke length is too short.
Does anyone know if the stroke length on the adjuster motors for xenon vs. halogen headlights differ?

I have bought Depo headlights in the past and have found the to be quite poor quality and the internals are built at the price point paid.
From my experience the Hela headlight assemblies are a far better quality and the motors and bulbs tend to fit properly.
My advise would be source genuine Hela and they will work as intended especially if you fit new adjusters  :y

I would very much like to have Hella headlights but I could not justify buying these considering the value of the car ;)

Not had the motors apart, but the xenon ones are about a third bigger. presumably beefier internals/electronics as they are constantly driven by the ecu behind the right hand headlight/inner wing rather than occasionally by a switch on the dash...

Depo ones are fine as long as you accept the compromises that the price brings ;)

OK, good information, thanks. I will check the part numbers on the fitted adjuster motors to see if they are the right ones. (After I have found out which item number it should be ;D)

As above, a very common problem.
It's easily checked: remove the bulb cover, and waggle the reflector with your finger. If it moves, you need new adjusters.
There's a guide for this.

I really hope the adjusters are ok because the headlights are brand new out of the box.
In which case, have the travel locks been removed? Various metal bars and cable ties iirc...

Thanks, very good question, will definitely check this with the mechanic on Monday. It would be both nice and embarrassing :-[ if missed travel locks prove to be the problem ...

The travel locks had been removed before mounting the headlights, troubleshooting continues :y

Doesn't matter, Omega headlights aren't handed just flick the lever inside for lhd or rhd.
