Hi

 

I have 4Motion with factory fit xenons, I would like to do this mod but my car has 6 indicator bulbs as has twindicators not including the 2 side repeaters. I used to have at least four hazard switches laying around, a mix of both types and typically cannot find one of them when needed! Will have to order one off the bay.

 

Any ideas at what the shunt resistor should be used for 6 bulbs?

 

Thanks for any advice.

 

Jay

150mR should be fine :)

Thanks NooNoo for the speedy reply  :rolleyes:

 

Great effort with working this out.

 

I have one more question if I may....

 

I have been looking at led replacement tail clusters which have resistor packs already built in for the rear indicators. If I were to mod the hazard switch would it be advisable to bypass the resistor packs or leave them in? Would still change the twindicators to LED of course.

 

Thanks again,

Jay

The 150mR is for LED loads only (side repeaters are OK).

Do NOT run ANY load fakers or normal front/rear lamps with this mod. The shunt will get HOT!

Whilst the shunt at 3W will tolerate considerable dissipation it will probably desolder itself.

Just need to be clear

I thought the factory fit xenon twindicators were fed by one bulb fitted in the centre?

I have never changed one so was assuming it was 2 bulbs!

Don't I look silly....

Thanks fellas.

No worries bud, I was always under the assumption it was 2 bulbs until a mate of mine changed his and informed me it was a single!

Guys sory if this should be a new thread, but I've recently purchased a pair of Cree LED side light bulbs for my R32, these were fitted to my car before, but one started to occasionally flicker, so as I was changing my headlights over I purchased and fitted a fresh pair, since fitting all of my indicators (no bulbs blown) flash really fast, but when I press the hazard switch they all flash normally, the Cree bulbs were advertised as error free, after contacting the seller he simply suggested I purchase their resisters to try and solve the issue. Any thiughts before I leave feedback for the seller?

 

TIA

Fresh sidelights and now you have no indicators?

I do have them but they are flashing fast, could it be the hazard light switch?

So you changed side lights for new ones due to a flickering one. Now your hazards fast flash...

Utterly bizzare. Are you sure all indictor lamps are working, using indicator stalk?

In hazard mode fast flash (bulb failure) will not work, hazards will always flash slowly (as long as at least 3 bulbs are working).

Im gonna take the side lights out tomorrow and see if they go back to normal...

Excuse my ignorance, but if u fit led bulbs to the indicators they will flash really quick, even with the canbus stupid ones. The only way to use led bulbs and not get fast flash is to either mod the flasher relay which is what noonoo has been doing, or fit some inline resistors to each bulb.

Is that why you're getting fast flash ?

Not fitted LED flashers in anypart of the car, I swapped over the entire headlight units, upgraded the DS2s for the Osram Nightbreakers and I replaced my Cree LED sidlights that is all. Indicators have been flashing cash ever since.

So did the replacement headlights have LED indicators in them? Did you check all lamps?

Oh right gotcha.

Did the indicator bulbs have halogen bulbs or LEDs fitted in there ? Did u check what bulbs were there before fitting the headlights ?

It's not too hard to pull out the indicators. I recently changed mine.

Just take the rear headlamp cover/ballast pack off, and the indicator bulb is a small twist fit type lock .




On another note I'm loving having led bulbs in mine now. The indicator flash is just so instant on/off its cool

Hi folks,

 

Just wanted to say thanks for the how-to guide, it has been a huge help for me modifying my hazard light switch to allow me to use LED indicator bulbs. The only thing I would say is to be 100% sure which version of the switch you have before you start stripping them down & attempting to modify them as I found out the hard way. I bought a brand new switch from GSF before checking which type my original one was and it turned out the untouched original one in the car was the easier-to-modify 'type 2' switch and the new one from GSF was the 'type 1' nightmare-to-modify switch.

 

Attempting to modify the brand new 'type 1' switch resulted in much swearing, burned plastic due to really bad access for soldering iron and eventually a totally FUBAR'ed switch! The copper switch contacts setup in that switch is mental and is liable to fail if you even so much as cough too hard on the contacts & getting them out of alignment! Don't mess with them!

 

My original 'type 2' switch proved much easier to strip further down & gave much, much better access for removing the original shunt & soldering in the new replacement resistor (from RS). I now have fully functioning LED indicator bulbs all round with no hyperlfash issues at all. The flash rate is unchanged and there are no issues with the resistor/switch heating up. My original 'type 2' switch has 'VW Made in Germany' embossed into it, has 4 prongs securing the front of the switch and 3 LEDs on a visible PCB behind this switch front. It also has white paint dots on top of the upper switch casing and on the grey terminal back at the rear of the switch.

 

Oh and another thing, always make sure you have a spare unmodified hazard switch to hand before you start attempting to mod your other one in case things don't go according to plan. I've gone through two of them now.

 

So thanks to NooNoo for the excellent guide & for doing all the leg work with regards to the best resistor rating.

Yeah, it is a bit tricky. Not for the feint hearted!

 

Remember to visually check your indicators on a regular basis.

 

Pleased you succeeded in the end.

@NooNoo

Nick, do you have a run down of how we can fit led brake light bulbs to the MK4 tail lights without upsetting the 3rd brake light etc pls .
