Is it normal?

Is it normal for the crappy headlights to dim when I hit the Window Switch?

I'm considering swapping my stock battery out from my 2007 to maybe an Optima Red/or Yellow.

What do you guys think?

That is actually a pretty common occurrence for most vehicles, not just Wranglers. My '01 Bullitt did it, wife's '09 Accord does it, and the Jeep does it.

Hope not, since my Bullitt was a Ford and Accord is a Honda.

But a chance to a deep cycle battery might help. Just nothing I'm going to mess with til its time for a new battery.

One of the first things you should do to your Jeep (after flipping your rearview mirror for better vision out the back) is replace the headlights. There are a ton of choices...but one of the most popular and effective fixes is to get a pair of Rallylights.

Your Jeep, your eyes and all the local critters that occasionally cross roads in your area will thank you for it.

Here's a link to their site:

Susquehanna MotorSports - High Performance Vehicle Lighting and Competition Accessories

And here are a couple of links to WF threads discussing other options, which bulbs to use, etc.

What bulbs for Rallylight headlight upgrade?

Yea, I am working on getting that now. I have been waiting for a few extra $$ in my budget to go ahead with this. Tax times right around the corner


Although I have to say, I can see decent with the stock headlights and fogs on. Just the headlights are crap though.

Check your alternator...have a voltage test done at Autozone or anyplace that does it for free. Buying a new, bigger battery has nothing to do with dim lights...just using the window switch makes your lights dim is a big flag that says your alternator is not putting out enough voltage.

X2, definitely follow up with NHrubicon's advice. The alternator should be pumping out enough juice to keep things from dimming, unless you're drawing a significant load.
If that checks out, check for dirty contacts, bad grounding, or the condition of the light harness and its contacts. Maybe its just clogged up with dirt or the dielectric grease has turned into muck. You can probably trace it down to something that will reduce the problem to where its not noticeable. At least.. I'm assuming that you are referring to some miniscule drop that most people wouldn't notice.

That may attest to some starting problems I have lately also.

Every few cold starts it takes a few seconds to turn over.

Hasn't failed me yet, but its scary.
