i think this is a repost but i can't find any useful info thru searching

i want to put fog lights on my ls, but i can't go about doing so w/o cutting out at least one of the horizontal crossmembers. Has anyone mounted the lights behind the grill? or under the front bumper. If you have them installed on your LS, what kinds did you get the Round Projector ones or the Rectangular ones?

Thanks
