H4 To H7 Upgrade

[mlh677]

Great thanks, have seen it as an option on the App but knowing in reality it works as expected is good to know.

Will give Auto Bulbs a call and see what they say, don’t really want to put it all back together and get bulb out errors then have to experiment and wallet-dent trying different options.

And you have no issues with indicator flash being less visible with a brighter DRL next to it?

I have no concerns, the indicator (standard bulb) still has good visibility.

Also, I am not a fan of DRL switching off whenever adjacent indicator is activated, but if that would be your preference once installed then an option to enable this functionality is available in Carista.

It's hard to capture in a photo, but below images were taken when I originally installed the headlights (before I switched to LED position lights):-

Just tried to buy them but they were sold already.. probably to someone on here!

Wasn’t me, promise! I had been following this thread for a while but was always too late. The set I found on EBay hadn’t come up on here yet and werent that well advertised tbh not sure how I found them. Paid £160 delivered.

Thanks! Pictures are really useful. Indicator looks plenty bright enough with LED DRL in

And yeh I also agree not a massive fan of dim or off DRL with Indicator on. So will leave that alone.

Thanks very much, think this answers the question that I need to get the correct bulb to ensure correct resistance so bulb out dosent come up, and can’t just rely on fixing everything with Carista or VCDS. Much appreciated.

Also if it makes a difference it’s a 68plate Highline Kombi.

Here’s what I fitted from Auto Bulbs Direct.
No bulb errors.

Sorry, it was me! I had been looking previously on Marketplace and they popped up on my FB feed. Will post pics when I get them fitted.

Oh that’s right post pictures and rub it in why don’t you

It was my own fault for not checking the forum for 12 hours!

Good luck with the fitting and hope they’re in good nick.

Found some time this afternoon to fit the H7s I bought for £70 from the post further up this thread. Was a simple process and the guide on here for removing the bumper is great. Really happy with the result. Much, much better dipped and main beam and better looking DRLs.

I used the Twenty20 LED DRL Bulbs mentioned above and they work with no errors and look great.

For the dipped and main beam I went for Osram Cool Blue Intense.

I’d recommend the upgrade to anyone that wants a massive step up from the H4s but may not want to stretch to LED.

How do those Osram Cool Blue compare to the LED drl in terms of colour match? I need some new H7 bulbs

They are not as white as the DRLs. I’d say they are nearer 3500-4000k. Quite a bit whiter than normal bulbs but nowhere near the LEDs. My DRLs go off when dipped headlights are on so they are not seen side by side anyhow.

Got on with fitting the H7 units today. All went without issue (even in mizzle, rain and 6degC) so thanks to the forum members for all the info and support to get this done.

Took 2 hrs including Carista Beta coding for dipped staying on with Main. I fitted all the bulbs beforehand indoors. Used Nightbreaker 150 in both + the same Twenty20 LED DRLs as mentioned above. All purchased from ABD. No bulb out errors on dash.

Something I hadn’t seen in any videos or pictures was where/what/how happens if you have Fog lights. Advice from forum members was spot on that there is a connector just in front of wheel on drivers side that needs to be disconnected. Eveything else lights etc is connected bumper so comes away when removed. Just gently pealed back the arch trim to access once all bolts were loose and had popped the edge of the bumper loose.

Some photos of the Fog Light connector to help anyone doing this in the future.

I swapped mine over yesterday, and no problems other than these

582 (7440) Twenty20 CanPlus LED Canbus Bulbs W21W (Red)

Twenty20 have released the next level of 582 CanBus compatible LED bulbs, the CanPlus range. These are packed with the latest market leading technology to eliminate those pesky error messages in even sensitive vehicles.

Firstly, they are huge and a real bugger to get in.

Secondly, I got a bulb out warning with them but today the warning has gone so probably a low battery issue?


I also fitted these

501 OSRAM LEDriving SL Range (W5W) LED Upgrade Bulbs (White) - Pair

501 upgrade LED bulbs from OSRAM's LEDriving SL Range offering a white colour output and more light than a standard bulb.

But one of the bulbs wasn’t lighting up, so I took it out rotated it 180 end it was fine, so don’t forget to check the polarity if you come across the same problem.

Just been looking at those, are the replacement caps easily sourced?

 

[dubber36]

Yes, they are a pretty standard part. I was missing one off the 6R Polo, so 'borrowed' one off the H7s in the garage.

 

[Bigsidavies]

It might be that one off the H4 fits and can just be transferred. I’ll have a look later when it stops raining as I still have my old H4 lamps.

Very kind if you Sir.

Very kind if you Sir.

I can confirm that both the large and small rubber covers are identical between the H4 and H7 lights.

 

[Cuffy]

I've just messaged him and asked for a quote to post to deepest darkest Wiltshire, fingers crossed he hasn't sold them.

Isn’t it the plastic cover over the dipped beam and DRL that’s missing rather than one of the circular rubber covers? It looks the same as an H4 one so would hopefully be a straight swap too.

That was the same too. But I thought the missing one was a rubber one so I mentioned those.
