I admire your creativity! It's all too easy to 'hit the plastic'
nowadays!

We in the U.K HAVE to have amber,front and rear and unlike you folks they have to be separate from the brake lights!
Most U.S imports here get aftermarket flashers 'Nailed' on to the bodywork and look terrible.
I'll be using L.E.D conversions in my A.D. for stop and tail lights with bed roll amber L.E.D.'s for my flashers.
I was lucky, my wife got me some as a birthday gift!
Nice job though!
