Recieved the Headlight Protectors from cgi today. I ordered them as in the past I have suffered the expense of a cracked headlight. I don't do much riding after dark, so ordered the "Clear" type as I intend leaving them on permantly. I have not tried them in the dark yet, but they don't look like they will distort the lights much. You can remove them, as they are supplied with velcro type stickers allready stuck in place. The glue on the stickers seems pretty strong, so you only get one chance to get them on straight. The perspex seems of reasonable quality & thickness. The profile / fit is good. I have seen headlight protectors advertised for £40, so on that basis they are good value (£14.99).
