Hi, 

 

I want to replace the halogen headlights, h7, to LED.

Which adapter do I need to hold the bulbs in place?

 

Thanks

You don't need any adapter, you should just buy H7 bulb. The socket is same.

 

PS: LED bulbs have focusing problem on reflector headlamps. Don't expect decent lighting.

Hi, lighting is fine...

What holds the bulb in place is the connector behind it, now the connector is not behind the bulb.
