If you go to your local craigslist, there is likely someone selling some LED cubes in the $30-$50 range. If you're on a budget, or you just want something you can slap on without worrying about theft, these are a great option.
I tried a set of $30 lights on my windshield as a moment's notice purchase cause I was going night wheeling that night and they actually worked out great. Plenty of light and very cheap ($30.)
I have since went crazy and bought the Rigid Dual windshield mount along with a pair of used D2's in HyperSpot that i bought from eBay, and D2's in the Driving pattern (craigslist.) There is a noticeable difference in light pattern, spread, and brightness. Is it worth the extra couple hundred bucks - Up to you to decide. I could have been fine, but I had the cash just dying to be spent and I know Rigid makes a quality product. With the knock off lights your milage will vary. My contact says "just let me know and ill replace them or if its more than a year down the road I'll just sell you a new one at cost."
Since my Jeep is not my daily driver and sits in the garage safe and sound all year, theft is not an issue for me. Seems like every week now Im hearing about LED's getting stolen off of someones vehicle. From their yard, to a stop at the grocery store - it happens. While I like the higher-end brands and see a value for their cost, theft would detour me from running them. If someone stole my $30 chinese knock-off lights, I wouldn't be so upset. Take a $1500 lightbar and I'd lose my damn mind.
The Baja design lights are a great product. I just don't care for the design.
Here's how she sits now. The mounts are easily removable, and I have them wired to 4-prong trailer connections underneath the cowl.
