I installed the Hella 450 kit on my Toyota truck because I wanted more light than the stock headlamps produced. I was amazed at how much more light was produced compared to the PIAA lights(12v 55W)I put on another truck. The wiring harness was not like the one pictured, but I didn't care because I had more freedom with where I ran the wires. Some knowledge of electrical systems was helpful as the instructions are somewhat lacking. I would suggest testing your work with a voltmeter as you go to prevent errors; the instructions aren't the best. Installation (professional looking)took about 3 1/5 hours. All of this is worth the trouble because the end result is the ability to see far ahead on very dark nights for a reasonable price. Even though the case is ABS, the complete system seems very sturdy. The lenses are better quality than others in the same price range. Great product!
