I don't believe the lights off hard rocks will work on the ps bumpers, the fogs that come on jks with the plastic front bumpers have different mounting points than those do
I would buy the 14 housing and keep the led bulbs as they would work, check the classifieds here there was someone that had a set for sale
I've got a set sitting in the garage if you want them.
You have the ones that will bolt right onto the PS brawler bumper? If so PM the price.
