Thread: Halogen to LED D4 Headlight Bulb Conversion

Plenty of room in there for heat dissipation.[ATTACH=CONFIG]175062[/ATTACH20211113_095517.jpg]

FWIW,we had Bi-Xenon on our old D4,they were pretty good,up until then,the best headlights i had ever had on a vehicle.
We did many trips after work,through the night,650K to the property,no spotlights,in our opinion, needed.

The new vehicle we now have,not LR,has LEDs,and they are way better than the Bi-Xenon.

Thanks for taking the time to do this Eric.

Looks like a solid option.

Cheers.

I'm not sure how true it is but I heard LR specced up the first D4s in Australia. My first D4 was AUG 2009 build, bought in Jan 2010. It was an SE but came with GPS, HK Logic 7 or 9 sound system and had Bi-Xenon lights. I found the lights were great. In fact not many cars had them in those days and I often got flashed, as people thought I was on high beam.

I incorrectly assumed that all D4s had Bi-xenon because they look identical. First time I drove the 2013 SE in the dark, I literally pulled over to check that the headlights were actually on . Wasn't a happy camper :-(

I've owned a sedan with adaptive LED .... they were the ducks nuts :-)

Sure are,and i thought Bi-Xenon were the ducks nuts....

They will put the spotlight guys out of business,but then again,i am sure many spotlights are just for show.,excluding,of course,long distant truckdrivers,and those that actually need them.

I’ve got the bi-xenon and have upgraded the infill high beams to the Stedi units. Pretty happy with everything but feel like I need a bit more down the middle an thinking of maybe one of these STEDI™ | ST1K 21.5 Inch E-Mark LED Light Bar on a number plate mount.

That's what I did although not with a Stedi bar, but still a single row LED. Makes a big difference.20190806_180740.jpg
