I saw the socket that would fit these relays. Problem was that none of them used 12 ga. wire and therefore they were of no use to me. As for my relays each one cost $12 since they are Tyco/Bosch and not Bosch style. The head light sockets were $10 ea. as I wanted a minimum of 14 ga. and most that I saw locally were 16-18 ga. Could also get weatherproof 12 ga. soclets for $12.

This is why I didn't bother with packaged assemblies as their wire gauge was smaller than 14 ga. in many. Even my power wire is 10 ga. since there is safety in thicker wire especially if you run H4 with their power consumption and heat created in wire.
