how bright should one foglight be?

[Per Lindgren]

Fog lights only use 21 watt bulb, same as brake lights. The reflector in
them are different, with chrome instead of silver paint, and more
focused, almost like a head light.

Personally, I put in 35 watt bulbs in both the rear fog and the back up
lights, both for safety (fog light) and viewing pleasure (when backing
up)
