Curtis I have the 3M stick on type on my LT & it works great. The stick on ones can only be used on the 99 to 04 bikes with the glass headlight. the 05 & up have a composite lens that the stick on will not work on. This info comes from the people I bought my guard from. I took a big rock to the headlight 3 years ago after I installed the 3M guard. It did put a small chip in the light but the film keeps it from breaking.CharlieVT said:I have the Cee Baily type. I wonder how much protection the stick-on film type would protect the headlight lens from a rock.
I had a rock break my headlight lens, cost a few hundred $ IIRC because you have to buy the whole BMW headlight assembly.
The plexiglass protector is cheap insurance IMO.
