Updating PY21W to LED DRL

[sloss]

Yes, sidelights and DRLs are totally different. see pic showing both LEDs.

In my last post the first pic is wedge type sidelights with resistor - they are not central in the housing - look carefully, it's slightly offset.

Second pic is to show yellow Fogs against the Sidelights - fogs are H7 bulbs.

Third pic is the DLRs - they are type 1156 Leds and need a resistor across them - they are central in the housing, look carefully at the pic, it's central.

Access on '08 3.0 TDi:

Offside remove aircleaner box then plenty access.

N/S remove 4 internal hex head screws to allow headlamp to move forward a few millimetres then use grandson with small hands to remove/refit bulbs after I soldered in the resistors.

Thanks Sloss, great info. So I'm thinking to just do the DRLs as the sidelights are rarely used, are there any plug n play 1156 LEDs with the resistors in place?

The 1156 with resistors I have seen are not as bright, maybe 120 lumens.
The brightest I have seen without are 450-480 lumens.

If you can be bothered, you can swap the sidelight and DRL pins round in the headlamp connector and recode for LED DRL, then the DRL is used for sidelight at reduced brightness and dims when indicating.

Can any one of you kind fellas point me in the right direction for some straight swap DRL's with the built in resistor? I came past a black D3 with LED DRL's on the M40 the other day and it looked so much better than hazy yellow glow.

I've had a quick scan on eBay but there's a minefield of ones out there so any pointers for some nice bright ones that don't require modding or re-coding much appreciated..
