Anyone tried replacement headlight switch from LRS?

I finally had the headlight issue get me the other night and it seems Ford wants a small fortune for their replacement switch. Granted, the backside of my switch is not melted (yet) and looks great (can it be saved?) - I am interested in this replacement unit:

1987-93 Mustang GT Headlight Switch, Reproduction at LRS - Same Day Shipping!

I checked out the Borg Warner replacement at Auto Zone and while it's very close to the original, the finish of the black plastic is not the same as OEM. Anyone know if the LRS unit is like OEM in this regard?

Thanks,
eric

You have to replace more than the headlamp switch. If it's not melted, it's probably okay.

Ford TSB 89-17-11 says this is caused by overheating in the headlamp circuit. You'll need to replace the headlamp and dimmer switches, several connectors, and then bypass the wiring in the circuit with new 12ga wire run alongside the original harness.

If you don't use the fog lights, you will likely never experience the problem.

What's wrong with doing the headlight switch mod w/o replacing any of the original parts (granted they are ok)?

the switch is fine, the problem is the current going thru the MFS(aka turn signal)

if you have had the lights flick on and off the MFS is hooped.

you need to do the relay or TSB or else you will damage the new MFS.

MFS is even more $$ if its still avail.

Well the lights were turning off by themselves but not flickering. I would just turn them back on myself and then I quickly remembered this was a common issue and turned off the fog lights.

they will come off and on, as the problem gets worse.

the slider inside the hi and low beams thru the mfs will eventually break.

its plastic and is begining to melt.
