Where do you clip the ground when testing under dash auto fuses?

Use the brake pedal bracket. I'd avoid using anything associated with the steering column.

Could this be used to test LED christmas lights?

Hi Tom, thanks for your inquiry, this test light could only be used to test 6-24V DC circuits, not for any AC circuits testing. Best Regards!

Where to buy spare bulb at? Or something similiar.

A spare comes with the unit but if both are blown I have no idea, You might just have to buy a new tester

Can I Just order the coiled wire with the alligator clip for replacement?

The coiled wire are Not available from this site, but they do show up on eBay occasionally.
