actually i have just bought an 06 sti , but assume the lights are the same as 05. iwant to turn off the daytime running lights, as it is hard to be stealthy with those hid's blazing away. dealer is no help at all.

There is a thread here on how to turn them off on a WRX. There is a relay behind the glove box you need to unplug. I've never seen them on an STi since they have HIDs. All the 04 - 05 STis I've seen don't have the daytime running lights. Not sure about 06 STi.

The 04 and 05 STi's dont have DRL.

I believe that the '06 STi really does have DRLs, (SOA has been saying that the '04-'05 had DRLs, but that is not the case) but the lights are very different from the '04-'05s. Wiring may be the same though.

I have never seen it claimed that the 04/05 USDM STIs had DRL (which is good, because they don't) but the WRX's definitely did have them. I believe also, all canadian STis have DRL but they don't have HID.

They are uber easy to disable, though.

SOA claiming that the '05 STi has DRLs (http://www.subaru.com/shop/specifications.jsp?year=2005&model=IMPREZA&trim=WRX_STI_SEDAN&category=SAFETY%20FEATURES) (The last feature in the list)

Here's the main DRL control unit from the WRX:

Im pretty sure the DRL's on an '06 is a completely separate light from the HID projector. There is a little bulb that stays on, then the actual HID projector, wich isnt a DRL.

The 06' Drl

THE 06' DRL lights are HID

That's it? Just unplug it and there won't be any CEL?

All STis and all Subarus since the early or mid 90's in Canada have DRLs.

No need to bump this two-year-old thread, there is plenty of information here on DRLs.
