The 6000K HID'S are the once you want ,any higher then that it starts to get blue then purple any lower then they go yellow like older style lights ,the light is the same like a late model W221's headlight ,once you installed them you might need to aim them a touch lower not to blind any oncoming traffic ,you also have the self dipping headlights for that when you have a weight in the trunk ,you know the little adjustment wheel next to the headlight switch .
I installed these into the low beam & fog lights section of the headlight ,installing the 6000K's into the Foglight section and when turning them on ,illuminates all the edge of the road and under in front ahead of you ,awesome look .
On my current S600 they are also with the high beam section but it takes to long for them to heat up ,about 6/7 seconds ,that is to long before you can see the full potential ,but once activated they are ok .
I know you like the car 100% but I recommend to get these 1st then you can slowly fix the stalk or what ever it is that is broken ,you wont even need high beam at all anymore like I mentioned already lol ,I wouldn't hesitate a second to do so since I know what these HID lights are capable of & I only have the 35 watts version in ,love to see what the 55 watt can show ,how far they will light up into the dark ahead of you or illuminate the surrounding area ,I'm tempted to get a 100 vat version for the high beam only .
Don't waste any money on thinking if you just get a Xenon bulb or a stronger like 100vatt globes ,they don't do nothing ,I purchased on special order globes that cost $145 each , you know where they are now , dumped somewhere in the garage as they as well didn't do anything to improve the early version w140's headlight vision , you can see more with a torch then a w140's headlight ,specially 92/93 maybe even 94 models .:thumbsup::nerd
