How To: Parking light only come on as Turn Signal

This is a FREE mod that takes less than 5 min to complete.

You can finally keep the ugly egg yolk from distracting from the pretty Halos.

Here is an inexpensive way to modify the stock 3157 bulb so just the signal filament of the bulb works. Just snip one of the exposed wires on the bulb socket:

There are 4 wires, 2 at each end.
The two outside wires are the High intensity filament, the two inside wires are the low intensity filament. Just pry up one of the inside wires (does not matter which end) and snip it off:

Got it, no more eggs in my headlamp

I would like to not use that bulb at all and instead use the 16" LED strip I got coming with the group buy. Is there an easy way to do that?

In that case you could completely disable that bulb and run the 3 wires going to that bulb into a dual intensity circuit then into the LED strip.

Oldie but goody trick for sure!

Ok, so I went to do this and my 3157A bulb and socket look totally different. There's not any filament wires and just 3 normal size wires leading to the connector harnesses before the bulb socket and bulb? Can it still be done?

If you pull your bulb out, you should have exactly what is shown, unless of course someone cut it off and replaced it with a normal bulb.

Just had this done the other day by JOE, didn't even know it was possible. Gives a whole new look to the 300C front end when the turning signals are off.

PS- also did another "mod" with help from Joe as well, and disconnected my high beams altogether... no more DRL's woot.

That was SRT666 that did the DRL for ya... I did the signal lights... after cuting the wrong lead the first time.

LoL Joe! I finally figured it out after pulling the bulb, mine just doesn't have wires like the picture it has metal filaments unwrapped. Clip, clip...piece of cake... thanks!
