You mean having all 6 lights on at the same time?
Thought all E30`s did it as standard,certainly all UK spec cars do!

On U.S. car's the law says it's illegal to have fogs and high beams on

You can modify your fog relay to give you the ability to have your fogs on with the parking lights without the low beams. Here's how it's done. Bear in mind there's variations with the model of the cars 88 and up cars only and it's not plug and play for all cars.
