John, very sorry to hear about the trouble you are having man
After reading yours I've spent some time here on the local retrofitting forum (retrofitting headlight here is a HUGE sport) and asked the guys if there is any 'magic tool' available to open headlights and all. Most said "screwdriver + twisting + elbow grease" but one guy with a high reputation thrown the tool below and said this will get any type of headlight opened in 10secs.
That seems like "The Tool" one would need to get the job done in a flash. Particleware, you think this would be The Solution???
I've used the mentioned large flat head screwdriver & twisting/prying method. Maybe not the best recommendation tho, really don't know. After reading about your experience I think I will be making this tool available to those interested in the kit I got. Looks more accurate
