Default LED conversion

Hey WAZOO!

For WAZOO guys I thought I would share what I learned for updating our exterior lighting and also offer my service to convert all exterior lighting.

CHMSL mod to LED can be done with no other modification:

Tail light conversion requires electronic flasher and I strongly recommend Sylvania ZEVO red LED. This LED will not create a hot spot in the middle of the tail light lens:

Front turn signal:

Front turn signal side light and rear quarter backup lights (both in clear lens):
https://www.ebay.com/itm/2X-1156-301...AAAOSweVNbYrue

Rear Back up lights (flanking license plate):

If interested pick up parts you need and I will install for you.

Tail lights do not require modification to light bulb sockets.
Other locations require touching up of bulb socket outer edge with Dremel. If perfect NCRS is you thing, I recommend tail lights only!

Hope it’s not too late. I’m having some issue with front turn signal. Hold off front turn signal until I sort it out. Rear, chmsl, front side and back ups, no problem.

LED turn signal is making the turn signal blink too slow. My guess is adding resistor may solve the problem but trying to avoid wiring mod. I looked for amber LED 1157 canbus error free but the towers look too big to fit the socket.

Question,

with the signal on, does the side marker flash? then with parking lights on does the side marker flash?

Funny you should mention this. Side marker is also problematic. I can get LED T5 to work for front side marker if I am using conventional turn signal bulb. However, with LED turn signal, I can't get LED side marker to work.
For now, I am running conventional front turn signal and side markers up front. I have side tracked to 200 amp alternator project at the moment.
Do you have any wisdom to share for front turn signal LED mod?

Wisdom? It won't work.. LOL. I know based on the 1990 FSM, the side marker bulbs run voltages both directions, something LEDs don't do. I have a 1996 FSM I need to check, as I have heard they changed the wiring of the bulbs, but not confirmed.

I built Goldcylon 3 sets of Side marker LED Conversions.. plugs into the harness then into the T5 bulb, so he is running LEDs in the front of the car with no issues.

With the circuits I made GC, they are low current draw with LED but should work with normal lamps (but not recommended).

Default LED conversion

Hey Yun,

I just want to add that I bought everything as you mentioned and all worked fine. I do have Euro lamps so the appropriate bulbs and colors, but same brand.

I ordered these for the front cornering lamps and received them today. They work great and plug right in with no mods.
