KW T660 aftermarket headlights

Personally I would just replace with OEM especially if they are cheaper. You can get OEM replacement from Fleet Pride, Truck Pro, etc for cheaper than through KW dealer unless KW has caught on to that by now and decided to be more competitive themselves.

 

OEM stands for "original equipment manufacturer" so that is what they come with from the KW factory. Just from memory Fleet pride sells Volvo replacement headlights for about $300 or maybe $400 a pair which is about half what you will spend at volvo. Don't know about T660 headlights just call around.

 

The way I look at it. LED is probably superior as far as light output but it's not going to be cheap. It will also be another plastic lens and I have yet to see any automotive plastic headlight lens that doesn't haze over. Polishing them out is a waste of time and effort. I don't know if haze deteriorates LED's output though I bet it does. That said if you are going to be replacing them might as well go the cheapest way. I sure do like my glass sealed beam headlights. They just keep cheapening everything these days.

 

JW Speaker LEDs are the best imo but they are super expensive. You can get them either glass or polycarbonate, I've had polycarbonate for about 2 years on my KW but I've got replaceable plastic covers over them. Some guys say that's a waste of time because you can polish out hazing on polycarbonate.

 

You can polish it out but will it last? Probably not. Not from my experience with our cars. I would definitely go with glass.

 

Problem with glass they break easily, at least where I live with flying rocks etc. even the plastic protective covers break (matter of fact I'm fixing one now).
I don't know if there is a difference between Speaker polycarbonate and the plastic on cars? Guys I talk to say they polish out on the Speaker LEDs.
