Re: [DML] high beam / low beam behavior

[Christopher Mack <christopher_mack@xxxxxxxxx>]

Owen,

Sounds like your dimmer switch may be at fault here..
The DeLorean has a 4 headlight system.  The high beam
bulbs are for high beam only and have one filament and
two contacts on the back of the bulb (1 ground and 1
12V+)  the low beam bulbs, on the other hand have two
filaments installed in them.  One for high beam and
one for low beam.  When just the low beams are on only
the low beam filament receivves electricity.  When the
high beams are on, the high beam filament of the low
beam headlight and the high beam bulb both receive
electricity.  If you look atthe back of your low beam
headlight, you will notice that there are three
contacts (prongs) on the back of the bulb.  One
ground, one 12v+ for the high beam filament and one
12v+ for the low beam filament.  

I hope this helps.. I don't know how to fix the dimmer
switch issue, perhaps you can take the switch apart
and clean the contacts.. my dimmer switch broke on my
delorean to where my high beams would be on all the
time even when the car was shut off.. I had to replace
my switch.... I hope all goes well for you getting
this  dimmer switch issue taken care of
