Im familiar with this EU part, but have only found it on ebay in the $80ish range, can you share your source? for $25 i would jump on it.I did it a year ago....
I installed the EU version fixture in place of the backup light. The EU version has a split red/clear lens and i have the red "rear fog red" lamp to the license plate light circuit. Works great. I did have to replace the plate bulbs with LED as the load was too much and the circuit would open. Took less than an hour and its an OEM part.
The light isnt "brake light" bright, but people stay back a tad further to keep it in view at a stop.
I had a pic but cant locate it at the moment. $25.00 light fixture and $10 bulbs
