These are inexpensive for a reason. I've bought them twice after the 1st time I thought well maybe I tightened them to tight and that's why all four cracked. Reinstalled the orange OEM lenses until the new ones I reordered came in. Those didn't crack. Carefully Installed making sure I didn't go more than hand tight the reordered ones rode maybe 200 miles washed the bike today and sure enough all four of these are cracked too. I compared them to the OEM ones and the pastic is thinner. Complete garbage. I wouldn't waste my 8 or 10 bucks on these to be disappointed when they end up cracked.
