My shop installs lots of HID systems. I won't be able to test an Elise/Exige until mine comes in April. but this may help. The headlight fuse should be replaced with one 5 amps higher. It is not the normal running of the lights that is a big deal. they actually pull less amps than the stock lights. It is the start up. Warming the salts in the capsule takes extra power. Hense the igniter. this can happen in a colder than normal morning, like Ground Loop said.

Also with the AM reception thing. Couple of things to try. Remember the ant. is grounded to the car. It may be necessary to run a seperate ground wire the the ground on the HID Balast. Also I have noticed some noise interference issues if the balast itself is not grounded to the vehicle. I would assume this to be a problem on this car with no metal grounded chassis parts available. You can try running a wire from the nearest ground source and grounding that to the body of the balast. This has taken care of noise problems we had in the past when we mounted the balast on a composite bumper beam. You can never have enough grounds. Balasts are sometimes so noisy that they "whine" audibly when they are on, and without a good ground that noise is induced into the radio. Hope this helps.
