He didn't remove the film, he just replaced the bulbs with LED's.
The plug in the same way as a regular bulb, except they are polarity sensitive (+ to +, - to -) or they won't work.I have bought bulbs that are 194 (not sure how to install the LED's... Don't they need to go into a circuit???).
Can't help you.The bulbs are blue, just need the red film to come off.![]()
