The problem is'nt the color - it's that once the lights FIRST turn on - they have a hint of blue -and are BRIGHTER than once they 'settle down' - so to speak - and they become - well - almost as yellow as STOCK!
I don't know what the hell the problem can be - but the next weekend home I'll bve sure to be doing a lot of swaping ns testing.
I loved the 7500K the ONE good bulb put out - i just wish the other bulb wasn't defective, and I could actually get a hold of the guy who sold them on eBay!!!
