After a week of use of my H4s with LEDs I’m perfectly happy to use them over the winter now while I decide whether to have a van change next year. They’re nowhere near as good as my car with its fancy LED system that illuminates different parts of the road automatically, but they’re good enough to be safe, even in the remote rural area that I live in.
 
Thanks, very useful summary! I wonder what the inconsistency is though with @Ethan Andrews positive experience (and beamshots) of the Twenty20 ones? I’m undecided whether to give them a go or not...

I did have a bit of inconsistency in the light pattern on my first post. But in the photos I submitted on here, I had adjusted the bulbs as one was at the wrong angle. And now I personally feel that the lights are miles better and nicer on my eyes for driving at night (not so tiring)

I would like them to be a tad brighter, but I get no complaints from other road users. But I am
considering upgrading further to HID units.
 
I found out recently just how tolerant other road users are to getting dazzled by oncoming traffic when I had to drive my old Landy 10 miles home with main beam stuck on. Only one person gave a quick flash on the entire journey which was half town and half unlit country A road. The Landy has been uprgraded to an alternator and halogen headlights so not the usual rubbish from a 50+ year old vehicle (I actually found it better than my T6 with stock headlights!). I felt absolutely dreadful doing it and deserve every swearword muttered by oncoming drivers (not really a problem for those I'm following as it's not the fastest thing on the road), but as stated before, only a quick flash from one of probably fifty oncoming vehicles and this was 120W straight at them, not some dodgy light scatter from aftermarket LED/HID bulbs.
 
I was following a car last night that had its rear fog lights on. At every opportunity they had the full force of the Tigs bi-xenons in their mirrors. Did they turn the blazing fogs lights off? Did they f***.

Paaah hah, we’ve all been there.
 
Cheepo HID kit fitted this morning. 35W, 5000K.

The difference in light shining in the garage door was as least double compared to the halogens and I'm pretty chuffed with the colour. Fingers crossed for the darkness test later.

Look forward to hearing what you think when you've driven them in the dark.

I'm starting to think that I might have been a touch harsh on the Philips Ultinon LED bulbs. Now that I've driven with them for a couple of weeks I'm starting to think they're pretty good. So much so that I took them out yesterday evening and tried the H7 halogen bulbs as comparison. I was shocked at the difference and then put the Phillips straight back in and thought "Actually, they are a fair bit brighter and much better light colour, maybe I was too harsh" I'm still not sure I would recommend them at £115, but maybe at half that price.
 
@dubber36 I'm guessing that the Hid lamps fit as easily as the halogen lamp ie. same dimensions but are there any issues with the driver and flying leads as this is the situation with the H4 headlight in particular. Saying that though there is an H4 Hid and there are plenty of 50 watt Hid retro fit kits for all H number lamp types... obviously we're all waiting for piccies!
 
Have a look at this, new review that's really interesting, hids vs leds in projectors and reflectors...

Fitting the bulbs was as straight forward as the halogen ones. There is a lot more gubbins with HIDs that won't fit inside the headlight. There is a grommet on the wiring harness, so I cut out a hole in the rubber cap on the back of the headlight for this to fit into.

They look very good . Looks like the hedge as been cut until you see the other photo. Do you get the warning on dash withHIDS .
 
I'd already turned off the bulb monitoring with VCDS when I had LEDs.
 
It was an experiment to see if HIDs were any good in these projectors. I didn't want to commit any more money, so went for something cheap. These had the most English sounding name.
 
@dubber36 as you’ve tried Leds and HiDs do the HiDs have a better fill of light across the beam. I have found that the leds are fine close up but they run out of light 100yds or so down the road.
 
The LEDs were just not powerful enough. A good fill spread of even light, but just no distance. Also, what light was put on the road was drowned out by headlights coming the other way. The HIDs are many times better. I'd go as far to say nearly as good as OEM xenons on dipped beam.

The problem with the THQ lights is the poor quality of the projectors. I think that having tried most options, HIDs hit the sweet spot with them. Anything less and all you've bought are some fancy DRLs.
