A question for you open-wheel gurus :)

[Keith Gregg]

I have recently been doing some laps with the totally excellent Formula Lights car from URD and was wondering if this car was raced with other makes of cars or if all the cars in a race had to all be the same etc...I have not heard of Formula Lights racing before but seeing as it comes in a road and oval versions then it could be an american thing.
What other cars should I be looking at putting on the grid with it (if any)?
Sorry for my ignorance in these matters :
Regards

...
Was it Schumacher that did a bit of indy racing in the past as well as F1?...I seem to remember that someone did...

A couple names that weren't mentioned yet: Jim Clark and Juan Montoya.
