Don't give up so fast. What did you use?
Mine were pretty straightforward, soft enough vinyl to curve without crimping.
I got a set from Tapeworks
. Five rolls (one extra in case ya screw up) for $20. You have to go VERY slowly and have a good eye. Placing a light at an angle helps - you can use the shadow as a guide. It's easier to do than explain. I liked 'em so much I got a set for the boxer.
I went with the reflective ones - they light up like crazy in flash and headlights but are much less obnoxious red and blue in normal conditions.
