LED taillights

I am still considering doing this to my rv but, i want to use the bargman kind that replaces the bulb with the entire lens its a sealed unit you just plug into the lightbulb socket and screw it in and it looks exactly like it was originally. Im just leary of the hyper flash syndrome that some coaches experience .. May have to just bite the bullet and get one and give it a try

Looks like a great idea! What bulbs did you use?
I tried these as backup light Bulb relacements but they were not nearly bright enough.

I would like to know what the good ones look like, price and where to get them.
