I have a 2001 B5 S4. The HID xenon headlights were recently stolen.
The entire headlight fixtures were completely removed from the car. I
would like to replace these with another set of HID headlights, but I
don't want them to get stolen again.
Are there any security measures I can take to prevent this from
Maybe some easy way is to use the hood alarm switch to detect that a
headlight is taken out/loose? I.e. some alarm wire through the headlights
which they have to brake/cut loose ?
I think now the alarm didnt went off?
I've once glued razor blades on the inner side of a grill of a VW golf 4. 2x
they took out the plastic grill and screwed the headlights out. (and simply
broke the upper mounting). Since then they didnt even tried anymore...
I like where your head's at. I am not above sabotaging my own car. If
someone is that crappy of a person that they will steal someone's
headlights, they deserve to get hurt. I don't care how; cut, shocked,
sprayed, burned, whatever.
To solve this problem I bought steel headlight brackets and a pinswitch
alarm sensor kit from:
Hopefully, this will prevent the theives from easily ripping the lights
out and when they try, the alarm will go off.
I understand that if the thief really wanted to steal the headlights,
they could, and only more damage would result. I'm willing to take
this risk because my insurance will pay for the damage anyway. I'd
risk more damage being done to the car if it will prevent the thief
from easily stealing the headlights.
I also considered adding a second alarm, as pictured here:
I'm interested to hear what anyone else has done about this. Thanks.

Be careful with that. Not only could you bizarrely get sued for injury
to the thief, but most likely if they realise your car has been booby
trapped and it's injured them, then they're likely to react by totally
trashing your car. I'd just go with somehow securing the headlights a
lot better, like drilling out the screw heads so they can't be
What about getting the outer lenses etched with the VIN number.
In the UK, anyone can get free etching, usually of all the glass
panels, at AutoGlass (CarGlass in Europe). They usually etch the
registration number, but you can ask for the last 10 numbers of
your VIN - they don't usually do the polycarbonate headlamps, but
then I havn't heard anyone in the UK having HID headlamps stolen
That is very true - however, the outer lens of the HID headlamp
(along with virtually all halogen headlamps for the last few
years) is NOT glass. It is actually polycarbonate - any
polishing, partiularly when trying to remove etching, will render
the headlamp useless, because of the fine scratches which you can
not remove. Just ask any motorcyclist how dangerous a scratched
Yes, you may be correct - but my suggestion of etching is merely
another deterrent, in the same way that visible VINs on car
dashboards is a deterrent, the same as DataTag and SmartWater on
motorcycles is only a deterrent, and ultimately car alarms and
immobilisers are a deterrent.
At the end of the day, the most determined of thieves will not be
bothered about ANY kind of security system. It will however,
deter the casual, opportunist thief, who, after eyeballing your
motor and noticing your differing number of security methods,
will probably think twice and move onto an easier target.
The other issue you both failed to answer was that my suggestion
was FREE, in the UK anyway. I don't know if the US car insurers
over the pond support car glass companies with free etching, but
I have noticed our US car owners seemed to be more adept with
Dremel tools, so they could even use that to etch the headlamps
