What are the stock lenses made of? I can't believe how bad they are after only five years. I am sure stock replacements are pretty expensive.
They're some kind of plastic ---- and it made sense to somebody...
I wouldn't buy a stock replacement. I don't like H13s all that much and the JK H13 reflector doesn't lend itself to much praise.
H13s are just a cost-cutting bulb and they show it.
H4s are subject to many of the same limitations but have a better build. And there are some really good reflectors out there that help make the most of them.
But, for our purposes, I have a different set of criteria for what motivates me.
We're not average drivers; we don't drive "cars" ---- we drive Jeeps. We go on roads but we also go on things that normal Americans don't call roads. My wife grew up in a very rural part of South America --- some of what we call "trails", she calls a nice road.
But we want to see the trails at nights. The rocks. The stumps. The drop-offs. We want to be able to tell the mud from the ice from the puddle from the sand, etc. All of the minutia that a street driver can be unconcerned about could be the difference between life and death for us ---- sorry to sound tragi-serious but you know what I mean...
That's why I want a good amount of light out in front of me. Reliable light.
I don't care about what looks good in a parking lot, what's trendy, or famous names in 4x4 history.
And I want legal.
