I'd like to upgrade my DRL angel eyes to whiter after-market bulbs. Question is, how do I work out what type of bulls I need? I assume I have Xenons, but how do I confirm?

If that's correct - are these OK? : BMW E92 E93 E70 E82 E87 M3 Angel Eyes eye White Led Halo Ring 20w CREE H8 Bulbs | eBay

Vehicle is '08 3.0SD (UK RHD)

Thanks
