I've got Whelen strobes and LED's installed on my 01 GP. Before people jump all over this, I am a career and volunteer fireman and have all the permits to use and display them. I've got the strobes in the front corner lenses and rear brake/turn lenses. I have a pair of LED's behind the front grills and a windshield mounted mini bar. The windshield LED was a late addition due to the lights in the front grill and lights are so low. Generally when I was behind someone, my hood line was below their trunk line and hence below their line of sight through their rear view. Thats why I added the windshield unit.
Go with the Whelen units, you may a bit more, but trust me you get what you pay for! The cheapies burn out quickly and their power supplies are garbage.
Make sure to check your local and state laws in regards to these units. The color of the lenses will make a huge difference if you are using them and get pulled over. From what I am familiar with, you are pretty safe in all states using amber lenses and ok with red in the rear only. But red, green, and blue require permits to be used firing forward, and white firing forward is generally legal only if you are an emergency type vehicle. But like I stated, every state is different, so check it out before you start using them. All it takes nowadays is a cell phone call to 911 with your license plate number and you can be in a world of hurt in a hurry, regardless if you state to somebody your police officer or not. BE CAREFUL.
I'll try to post a video or at least picts of them when I get a chance.
