You will not be disappointed with a set of well done retrofits. I guarantee it. It's night and day. It's so noticeable, I won't own a vehicle without a set. Just from the sheer safety perspective. The width and clarity of light is very impressive.
For instance, on my F250, on a two lane road, I can light the road evenly, without any break up in light, past the ditches on both sides of the road. It even goes further than the ditches all the way to the treeline. It's like a blanket of light from treeline to treeline. It's impressive.
though it's hard to photograph. and photos of the output are misleading.
I can see the eyeballs on a buck gleaming in the light way off into the ditch, way before I need to start slowing down or react.
you will never get that kind of performance out of a plug and play kit or a bulb swap. been there done that.
I used to drive 30k miles a year on two lane roads most of the time going from power plant to power plant. I spent the money from a safety perspective alone.
EDIT: And in addition to the performance, it reduces the glare to oncoming traffic. Unlike all the non projection type of lights. The lights have a cutoff line, above the line is barely any light. Below the line is 99% of the light. Hope that makes sense.
I can get really technical with this stuff but it's not necessary. just google "RX 350 projector cuttoff line". That is sufficient to explain in plain english what performance lighting is all about.
