Reducing radio static from HID's ....What's best?

Post by BIG F@ TW@ » Thu Mar 14, 2019 10:00 am

Now I don't listed to the radio that much, however when I do I don't want the signal to be interfered with by my HID's. I've tried ferrite coils, not much success. I haven't as yet grounded the ballast to the bodywork which is my next thing to try.

I've read about covering the ballast with tinfoil but it sounds a bit daft. What other solutions have you guys done?

I had cheap rubbish and not so cheap better quality hid kits through years and now factory xenons retrofitted on my last two cars, and never had any problems with radio. Can't it be some kind of wiring issue?

The more I'm looking into it it looks like grounding the ballast will help, and possibly using grounded braided hose cover will help. It's all good fun....

As above, a higher quality HID set (ballasts) is probably the answer. What have you got at the moment, where from, how much were they? Way back in the mid 00's most HID retrofit kits used 'dumb' ballasts, getting a modern canbus compatible set (although not needed on the B5.5) might help as the electronics will be better. Saying that I had my first set of HIDs back in about 2005 with a great big clunking set of old style 'dumb' ballasts without issue.

Saying that, the aerial bases are amp'd and suffer from water ingress, a problem I've had which, could also be worth a further punt. Also, assuming you have an after market HU, you do have the little external tube shaped thing that does the job of amp'ing the aerial output?

The lights came with the car. But I've not securely mounted the ballasts so I will be doing that first as a ground.

As for the HU pipe I don't know what you're on about there haha

The aerial is new, I installed it and ensured it was powered.Image

The thingymabob...

If you have an aftermarket HU and not one of these then radio reception will be cack. (assuming it is an OE aerial)

Oh yeah if you'd said an aerial booster I'd know what you meant. I have a few of those, always use them.

Never had the issue with HID, I would certainly recommend Morimoto, my 5five ballasts are the best Ive ever used, the current ones would be XB35 or XB55

No problems with my led headlights, no ballast or loads of wiring too...

Morimoto are hard to find in the UK though, I got mine second hand very cheap.

A quick look on ebay : https://www.ebay.co.uk/itm/Morimoto-XB3 ... SwENVcBHnP

Amp are the 2 round connectors most folks will have for their H1, H7 etc bulbs. 35W is more than enough for most projectors with good ballasts, 55W is sometimes considered too much and might degrade the projector lens and reflector surface over time apparently.

Also, often Hylux are referred to as pretty good choices : https://www.ebay.co.uk/sch/i.html?_odkw ... t&_sacat=0

These are also supposed to be good : https://www.retrofitlab.com/hid-ballast

When I fitted the Morimoto it was immediately obvious that they were brighter, start up quickly and so far theyve been very reliable.

There are ballasts that are now what is termed speedstart but just how quick that is who knows.

Unfortunately there may be a vast array of cheap ballasts, but getting a solid choice is very hit or miss, I used to buy the kits in the £50 range and even a few of them let me down, from now on I would only use aharon, hylux or morimoto etc.
