Definitely going down the quality route Rick. The criteria that i have set for these is that when they are not lit up then they should still look as they came with the car from the factory, no hacks and bodge-ups in the assembly of them, lets face it they are going inside a clear lens for all to see, if its not good enough for my car its not good enough for anyone else's either. Its important that the LED's used in these DRL's are high powered and low temperature with a long life. I can get low quality LED's at 10 a penny but they wont last and wont really be bright enough for DRL use without a reflective silver background holder and the Zed's reflectors wont allow that because of the internal width, bearing this in mind the ones i have chosen fit the bill precisely and are very bright at up to 25lm per LED, the downside is they are hard to get a hold of and a little expensive, but with a manufacturers proven lifetime of 15k hours its the only choice.
Zed's DRL's look the dogs "doodahs" cosmetically and functionally, these wont be any different... watch this space..
