HELP with new DRLs

Hi guys.

So I recently bought these LEDs..
http://www.ebay.co.uk/itm/VW-SCIROCCO-D ... SwGvhUEHy8

I know people haven't had much luck with these sorts of things with them blowing after 6 months etc but I thought I'd give them a try.
I really wanted them and thought they looked much better than just a standard single white LED.

So I fitted them today and they are pretty much perfect, apart from one thing..
They are FAR TOO BRIGHT! They are even out shining my Headlights.

This photo really doesn't do them justice.
Believe me they are bright! I used to have a HID conversion kit in my old car.

I put in an in line fuse and knocked the power down a bit with a 2A.

This toned them down a bit as they probably had 10 amps going through them before it.
I would still like them to be a bit more subtle and think right now they would be a little blinding to people if I was driving right behind them.

It appears 2 amps is the lowest you can get for mini bladed fuses.
I'm going to try blacking them out with some tint and see how that goes. Thinking 20% black tint?
If that doesn't work I'm out of ideas and would rather get my money back than have dazzling lights.

Anyone got any suggestions to take the glare off?
Any suggestions would be appreciated.

A fuse will not restrict the current and as such control the brightness. It is there to stop the current exceeding a pre-determined value and blowing to protect the wiring.

To reduce current you need to add the appropriate size and power resistor. Look up Ohm's Law if you are not familiar to calculate the value and power rating. The lights draw a specific amount of current based on the power rating.

Also, DRLs are supposed to be dimmed or switched off when the headlights are on.

Totally agree with that. And use some connectors with waterproof seals otherwise you will get corossion problems very soon.

You're right, why didn't I think of this.
Ordered some resistors!
