I originally purchased multiple pairs of BD Squadrons. In anticipation of trip to Rockies over the winter, purchased these replacement lenses for enhanced adverse weather visibility. 1st - they work well. 2nd - they are NOT street legal. While I originally thought the wide cornering lens may service as passable fog/running light. The only reason less oncoming traffic flashes me while using the amber lenses is that traffic knows it's not my high beams. But they are very bright, and still blind oncoming traffic even when aimed (moderately) down. But damn, I love my squadrons and these amber lenses definitely help during rain, dust and snow. I just purchased a pair of Diode Dynamic SAE Fogs for street legal amber lighting...just in case Im asked. :)
