Valeo Bi-Xenon Euro Spec headlights (B6)

[Dolphin S4]

I have the euro spec bi-xenon headlights that ECS tuning carries (b6 s4). Actually they came on my car when I bought it - but I can't seem to find the part numbers for the bulbs. Looking for the low beam part number and also blinker part numbers. Thanks for your time.

low beam should be a Xenon HID D1S bulb

Thanks, Bump for signals

The low beam bulbs should be D1S. Make sure to use only authentic Philips or Osram D1S bulbs (there are many counterfeited ones sold on ebay, amazon, etc..).
Using low quality aftermarket D1S will result in ballast failure since Valeo ballast is very sensitive.

If you need bulbs or ballasts or both, check out hidconcept.com and don't forget to use the coupon code 'PRESIDENT10' for 10% discount on $50+ order or 'PRESIDENT20' to save 20% on orders over $200.

For turn signal, it should be 3157.

I'm running Osram Xenarc 66144CBI HID Bulbs in my e-codes and highly recommend!

I have ziza 5000k D1S ready to go in for spring. Any good? Or chuck em

I'm not familiar with the Ziza's, but here's a review I found. I went with Osram because I wanted the best, and if I've done my research right, it's either them or the Philips Ultinon. I just happen to have a dealer account with access to the Osram's so the price was right.

Osram CBI D1S has very good color (5500K) with up to 20% more brightness.
If you want more brightness, you can also check out Philips X-tremeVision D1S bulbs that give up to 5000K color (starts at 4800K when new) with up to 50% more brightness.
We have both available. :D

For turn signal, it should be 3157.

Turn signals are not 3157 on E-Codes, which is what OP is asking about. 3157 is a dual filament bulb for park/turn. Euro lights have city lights in place of park lamps, totally different bulbs in a different part of the housing. They have a single filament turn bulb with a bayonet base. I don't remember the bulb number but I too had to dig deep to find it. I'll try to find the thread where I got my answer.

*ADDED* It's 7507 (PY21W). Asymmetrical bayonet base, single filament, amber bulb.
