Replacement Headlight Switch to Dim LED Guages

I couldn't really find anything that specifically said it could, but I am looking for a replacement headlight switch that is also able to dim aftermarket guages with LED lights in them. The factory switch obviously doesn't have that low of resolution and it's either on or off, but getting them on without the dome light coming on is difficult. I have Autometer Ultra Lite guages that I switch to LED bulbs. Autometer has a separate add on unit to dim them, but I'd like it to all be controlled by the headlight switch.
