LED Bulb Replacement
GTO69JUDGE=
,
29 November 2002=
Currently there are no LEDs that are a direct replacement
for late model F bodies, pickups, or other vehicles that use 3157 bul=
bs.
APC
makes a LED replacement which they claim is only for Chevy use. I have
not found a car that they work for yet, and they certainly don't work=
on
Camaro or Firebird models. All they do is blow fuses when plugged into
the socket. The reason they blow fuses is because their internal wiri=
ng
is different than a normal 3157 bulb.
I will describe how to cut open the plastic bulb housing, remove the =
bulb
and wire assembly from the base, reposition the leads and reassemble =
the
unit. This is actually a very simple procedure.
The bulbs (part #50.4050.C) are made by APC (www.4apc.net) and are available from
J.C.Whitney and Pep boys as well as many other auto stores for $8.99
each. Be advised that these LED replacements will give the "inst=
ant
on" effect of LEDs, but they are not as bright as the standard #=
3157
bulbs.
Start by GENTLY clamping the flat part of the bulb base in a vise. Us=
e a
fine (32 teeth) blade in a hacksaw to carefully cut the clear plastic
housing. Cut a groove just below the printed circuit board that the L=
EDs
are monted on. You want to cut only deep enough to cut through the wa=
ll
of the housing. You will have to rotate the base in the vise to cut t=
he
other side.
Straighten out the bent over leads on the base so you can seperate the
two sections. Exchange the position of the two INSIDE leads.
Clean off any plastic debris from cutting and apply a thin coat of
plastic model glue to the cut surfaces. After guiding the leads back =
into
their correct holes, squeeze the housing back together until the glue=
has
set.
Since the housing is now about 1/8" shorter, clip that much off =
the
end of the leads and bend them over as they originally were. Use your
original glass bulb as a guide to show you which way to fold each lead
over.
After the glue has dried, it is ready to use.
Note that if the bulb does not work after installed, rotate it 180
degrees in the socket. It will only work in one direction.
