Wiring is easy - just solder to the motor terminals but.............

the lights are the right spacing for the Scalextric car, it is extremely unlikely that they will shine in the right place for any other car and you will have a job fixing them to the Scale Auto chassis.

Thank you Brian, I think after reading Jeremy's comment I had a better look and realised I should probably by the one's recommended from Slot.it.
When I get them I will double check instructions and then probably triple check on here with you guys when I solder them.
