Thread: Driving Lights - D3/RRS

Thanks - I wonder why the lens is still in front of the halogens because the lights would work a bit better without them. The halogens are only 55w in high beam as well as low beam.

I thought Bi Xenons were standard on D3 SE and HSE and on RRS but obviously not.

Those HR7 HIDs look the goods - probably 55w (the OEM LR ones are 55W) and 4300k colour. I wonder if the shields are needed in view of the lens - I don't know.

55w 5000k HIDs in the high beams should also be OK.

Cheers

Good point, as the halogen globes don't have shields. If you were to get a kit with H7 globes you could try them in the low beam and if they produced excessive glare just use them for high beam and get the others for low beam.

On your advice I have bought these - 5000k H7 to initially put in the low beams. Dunno how to test whether they will be too high or not - guess test it by the number of flashes I get when driving around.

If they are too high I will move them to high beams and get the H7R HIDs for low beams. If the normal H7s are OK I will get the same for the high beams.

I bought the 5000k H7's kit for my Halogen High beams, fitted them already.
Look so much whiter & brighter.
I have not been able to drive my D3 as I am not allowed to drive for a 6 week period until I see my doctor again.
Less than 2 weeks left to go
I'll report back then!

I'd be inclined to compare the light patterns / cut-offs on a wall after fitting the 1st, and I'd do the left one because of less interference with the other. They might flash on startup, so either get the headlight specs changed to bi-xenon or just put up with the initial flashing.

Flashing??? I knew that HIDs might take a little while to get to full brilliance but what is this flashing. Also do the HIDs cause a fault message and if so how is this corrected (again LR being too smart for itself - the lighting system really does not need to go through the main computer system).

The flashing, if it occurs, would be due to the lights being momentarily switched off because of unexpected higher current being drawn by the ballasts whilst starting the globes than normally required by 55w halogens. Changing the light specs to bi-xenon prevents lights upgraded to bi-xenons from flashing, but as they're only 35W, 55W might still trigger a suspected excessive current shut-down.

I've only read about L322 RRs giving globe fault messages.

So it is the usual D3/RRS computer having a hiccup over nothing rather than there being an actual issue with the wiring and its ability to support 55w HIDs.

When mine arrive I will see how they go. I haven't found any aftermarket Bi Xenons that will fit without having to pull the light fittings apart to replace the lens with the lens supplied with the kit.

Thanks for all the information you have provided - it has been very informative.
