the best were the 360-degree units, but even those were at best 80% of the power of stock. The projector (item 2) would have been maybe pretty good with a clear unfluted, unhoneycombed lense, but not with what it had to work thru. I did not bohter with item 1 as they were 1.5 W vs 2.5. I am going to look at upgraded halogen bulb, but may just get under the car with the hella.
