[Biturbos4] Thermostat and Headlights

[alan cordeiro]

Greg

With engine running and headlights on, stand in front of the car and look at 
both headlights for brightness. If you see one of them very dim, it may just 
need one new D2S bulb for the side that's weak. I believe if they just flat 
out don't light, you get the bulb warning on the cluster display.

Let me know if you have only one bulb to change...I can send you one 35 watt 
D2S, 4300k color  ( have two lying around somewhere)

I now have Valeo E-codes....with DDM 55 watt ballasts and lamps  (using 5k 
color lamps for best compromise for brightness and whiteish color).
