[DML] Re: Tail Light Bulb Number (Modified Boards)

["content22207" <brobertson@xxxxxxxxxxxx>]

For *LESS* than $20, you can modify your tail light boards as follows:

Replace the single filament sockets at positions 2 and 4 with dual
filament (1157 bulb) sockets. This allows you to burn one filament for
tail, and both filaments for brake. 

DeLoreans look ridiculous at night with only two paltry lenses
illuminated.

The former tail light socket (position 3) can be tied to the brake
circuit so that every red lens lights up. To recap:

Tail lights: Positions 2 and 4
Brake lights: Double bright positions 2 and 4, plus position 3
(everything red)

Note that I also have a third brake light visible through the sunshade.

This is a rear lighting package much more consistent with traditional
automobile practice.

My turn and backup lights are still factory original.

stays illuminated continuously when your parking lights are on is the
center bulb on the board.  ALL other bulbs are 1156 bulbs.  This is
also the tail light section that is widest on the car, and the only
one that should have a reflector in it.

sockets call for a 32 candlepower (the equivalent to somewhere around
25W), *except* the running light bulb, which is a type 89, 6
candlepower (about 5W) bulb.  Since the original is pretty dim, Rob
calls for a 5008, which gets you almost the same bulb in 10W.  Putting
one of the 1156 bulbs in the socket designed for the smaller bulb will
eventually melt the reflector inside.

missing reflectors because the tail light cluster (easy to get) was
replaced with no reflector (hard to get).
