    Relay
  

*by J***N on Reviewed in the United Kingdom on 13 May 2022*

Bought for my 4x4 which had a rusted terminal so needed replacing, these ones where good value and just like all the other relays so a straight swap, being two in a pack the other one is going to be used when I fit some extra lights.
