Update:
The manufactuer contacted me and he is willing to make special metric version of his Low Pressure Brake Light Switch.
It runs on a 4 amps and he believes the two can handle the 8 amp load. To insure the switches will not burn out he also recommends a relay/regulator.
The minimum order would be 500-1000 units. Anyone interested?
Another thought I had was to install the OEM switch and attach a regulator on the 8 amp load to the switches, this should solve the swithes' premature burn out issue like this:
How do you guys feel about either solution.
Will do research on regulator/relay for the 8 amp load.
