Buy a spare set of frames if you are worried. Worst case, you can swap your old frames/reflectors back in and you'll be good to go.
If you're really worried, buy a set of beat up headlights off ebay/craigslist/these forums/junk yard and cut those up. Restore the lenses while you're at it. You wouldn't believe the difference it makes in light output.
