[DML] Re: headlights

[David Sontos <dsontos@xxxx>]

Normally headlamps are made so you can not switch the lamps to a higher wattage
lamp. This is done by arranging the terminals on the back of the lamp in a
different orintation. If in fact you have not modified the connector to fit
these new lamps than it is safe to say that the lamps themselves are wired
opposite of your current lamps. The low beam terminal is now your high beam
terminal, which is why all four lamps come on. You cannot use these lamps
without rewiring your lamp connector.

The other concern here is DeLoreans already have a heat problem from the
headlamps warping the front facia, with higher wattage lamps you may be looking
at a fire potential.
