I recently purchased a set of k2 smoke fogs. I have them installed and im using stock light bulb. They have been on for maybe 3 weeks now and today I noticed that theyre beginning to melt. I have a set of his extreme 6500k that im looking to install in the fogs. My question is this, Im going to get a replacement set from k2 and Iam wondering if the hid bulb will burn cooler than the stock bulb? If so, im thinking that should solve the problem. Anyone know what im talking about? And robb, go ahead and throw your .02 in since I know you will. By the way, No there not melted from the sun like you claim yours are!
