Thanks for the reply Andy you have just confirmed what I already know if the Xenons are to stay I will need to source a replacement unit. Its only the nearside thats knackered (at the moment) I assuume it fell victim to the recent cold weather. I have to say I've never been that impressed with these lights even when they were working and I've had the car 9 years. I always thought the conventional lights on my previous Senator where much better the built in driving lights were excellent. I also hate the plastic lenses they have now. Thanks again for the advice.
Any replacement light unit will at best be as old as yours. These adjusters get very brittle and even if OK when posted don't always survive being posted. Ally adjusters are the way to go.
I had a couple of Senators over nearly 10 yrs so know what the light output is like from them, & I had 85/100Watt bulbs in them .... they were that good as standard

. Of all the comparisons with the two cars, the HIDs of the Omega IMO beat Senator's hands down. Unless your lights are very yellow'ed (which I doubt a 98 would be) I'm at a loss at to what problem you might have.
