My high beams weren't working so I replaced the switch. Dave said it could have been because higher wattage bulbs were used. I put stock high beam bulbs in. Lows are aftermarket HID with ballast. Can I leave them or should I go back to stock low beams?

Many thanks

The high beams in the UrS4/UrS6 DOT (NAmerican) headlights tend to work just fine with the stock bulbs and wattages so most people do not "upgrade" them. *IF* they do go for higher wattage bulbs, it is wise to relay them to avoid running too much current through the column light switch.

The DOT low beams, on the other hand, by consensus, tend to suck the big one. Lots of folks have upgraded from stock bulbs to alternatives. The current (no pun intended) upgrade for the 9006 low beam projectors are HIDs, typically in the 4600K to 5000K range. Initially these HID kits were over $500 but in recent years they can be bought for well under $100 per kit. So end up with issues with the Autocheck registering a bulb out fault because of the lower resistance of the HID system.

So, bottomline, if they are working well, you will probably want to keep the HIDs that you have.

Thanks, Dave--good news. They are working fine & I have changed so many things out on this S6 that I am happy not to have to do the low-beams.
