    Bulb model for DRLs and Front Turns on CTS w/OEM HID

    What are the bulb model #s? I was thinking of replacing the DRLs with something brighter to match the rest of the lighting and the turns with LEDs. Called cadillac parts and they didn't even know the bulb number. Anyone recommend any LED DRLs and Turn signals for this car trim?

    There's a couple write ups with before and after pics about this in the CTS-V forum.

    I ordered the Hoen H11 Xenonmatch and the Cree 5202 LEDs today.

    It's all about getting the correct socket which is H16 for the DRL's. I got the 30w Cree on ebay for about $50 and they are really bright. I do see they have 50w now.

    That doesn't quite give me enough information for the turn signals. Not sure what that model # is.

    I have the Hoen H11 Xenonmatches (had them for 3+ years, one finally burned out). Might just get another one. Contemplating HID. That's what got me looking at all this again... These links don't mention the amber turn signals, however, or perhaps I missed something. I want to replace those with LEDs as well.

    The above post mentions 11W. You got 30W. What wattage do you recommend and why? I just want them to last a long time and be whiter.

    Thanks everyone for your help.

    I don't have any recommendations as it depends on how bright you want and how much you want to spend. I bought the 30w because it had the most wattage at that time and $50 seemed like a decent price. I am very happy with it. If I had to buy it now I would probably go with the 50w.

    i did see in one of those threads that an led turn signal will blink very fast because the low resistance makes the car think the bulb is burned out. decided to keep mine stock.

    Yeah, I figured as much. I assume to get it work right I'd have to add resistors. I had the same problem in one of my other cars, however in that car I just replaced the flasher with a model that doesn't increase the blink rate on low resistance. I don't think I can do that on this car, but adding resistors should help, and these days you can buy LEDs with extra resistance built in (for some bulb types).

    So, this weekend I installed the LED lights from that ebay link and I would seriously recommend going with a different brand.

    I spent half an hour trimming excess plastic off the bulb so the connector could plug in. When I finally got it installed, the lights are barely bright enough to be seen. They are visible only at certain angles but 90% of the time, it looks like the lights are off.

    I found some 360 degree LED's that I'm gonna try next so we'll see what happens.

    Here's the one I got on ebay. They fit perfectly and really bright. They are from china so it took awhile to deliver http://www.ebay.com/itm/2x-CREE-SMD-...E:L:OC:US:3160

    Yeah, IDK if you want to try them or not but the installation hassle was not worth it for me. weather permitting, I'll take some pics for comparison so you can see what they look like.

    so heres the update, the link i followed was for 5W bulbs and our cars take 19W OEM. The seller I purchased then from (cortse) has emailed me and offered to give me a free upgrade to a higher wattage bulb! They have 16W bulbs so I'm gonna try them out. I'm thinking these should work out.

    The ones I ordered (from that same seller) are supposed to be 11W, like the ones the other guy in the other thread used. Hopefully they will be okay then. Should have just gone with higher wattage in the first place... Just thought since those worked fine and looked good for the other guy they would work fine for me...
