I got Sylvania LED's off the shelf at O-R'iley's, and they are sublime. Cannot go back to halogen or other HID's.

 

I will dig up what I can find.

I may have most of the bulb numbers I used. I got them from Summit Racing accept for the front Turn and DRLS up front.

 

Sealight makes a great LED bulb.
It is recommended to get an LED with a cooling fan.
Regardless of what a vendor may advertise about their "fanless" designs, I would caution LEDs without fans will not last as long or reliably. They often start flickering and next will fail

If the Sealight bulb fits, it is worth the money.

I've used Sealight LEDs for 3 cars now and some 6 years.
After auditioning and trying 11 other brands, Sealight has several models that performed well and lasted. There are two or three other brands also that do well.

 

Head lamps 9005 are ORC-V5239-001 and 9006 are ORC-V5240-001

Front DLR and Turn lights are I think 3157 LED but in Switchbacks. they will be yellow in the day time and white at night or yellow when turning. I do not have a number on these and one of the vendors here had them. They will also keep you from melting the housing for the light. Check yours as if it is original likely it is cracked or melted.

The Relay 30 Amp. DAK-RLY-1. It is a 4 wire but you will only use the Black and White wire and cut the other two off.
Extension Wite Harness 2 Piece 9005-9006 Headlamp socket connector adaptors. from amazon. You cut this wire and splice the relay in so it is plug and play on the car. Bolt the relay to existing stud on the passenger side. only one relay is needed.

You may want to double check me on these as you order as I did this from memory. You can sub in many other bulbs for the side and rear but I would stick to the Oracle bulbs for the head lamp.

The relay install is on the site here as a member posted it and that is where I learned what to do. It is a much safer and better way to do this. Otherwise the headlamp will not close unless it is on bright.

 

I think at some point I'll need to step up to something brighter, I don't drive all that much at night and only use the Interstate highways at night so their pretty well lit. But if you live rural you most definitely need more light of slow down a lot, I went the LEd route on my C6 and used a forum vendor and after $1059.00 was totally disappointed. Still feel the sting from that episode so getting better light at night is moving forward with caution now !

 

BTW. Some LED's allow you to customize the color temp. One of the ones I had came with film you could wrap around the bulb--in order to raise or lower the pure-white they emanate by default. HID/halogen/xrypton/xenon you can't do that with--because you can't even leave a fingerprint on the bulb.

 

I bought the ACA Bi-LED (or whatever the heck it is called) from George back when the business operated as Radio Flyer. Company is now operating as Sharp Light Innovations. So my story is:
After reading all kinds of opinions about what kind of aftermarket bulbs were ... Good, Okay, Horrible, ... I figured that trying this and that and some third/fourth solution was a way to make myself crazy. So I knowingly went with about the most expensive offering at the time. The factory headlights are DANGEROUS in my opinion. A car that goes as fast as the C5 needs really good headlights. The upgrade from Sharp Light Innovations is as good as anything coming out on new cars in 2023.
If you want to tinker around the edges and see if some Sylvania (for example) bulb works for you that might be a way to save some dollars. I have been really pleased with the one-and-done upgrade available from Sharp Light Innovations.
Hope that helps someone.

 

^^ This. I live in rural Florida, DARK is an understatement when describing the back roads here at night. In the summer the only enjoyable time to drive without being baked alive is at night. The Bi led's I recently installed from Sharp Light Innovations are easily the best upgrade I have done to my car as far as performance and safety.

 

I tried everything before and only got marginal improvements, eventually bit the bullet and bought the sharplight ones.... WOW WHAT A DIFFERENCE is all i can say, wish i would have just done this from the start. But it's expensive for sure but worth it!
