Really? My x has to go to the dealer this week for some minor issues I'll have them check the battery. I asked Lux if they drew more power than the OEM bulbs I was told they use less power.

They do, but for whatever reason my X was more sensitive to them than the old bulbs. Sure enough though, I replaced the battery and all is well!

I have a thread out here on the topic to and it has the entire story:

It was the battery. My question is of they use less power then how come the stock bulbs worked before I installed the Lux? But when I put the stock ones back in they stopped working. Strange.
