Installation overview of aurora Angel Eye kit on a 2003 BMW 325Ci.
We have seen lots of Angel Eye kits on the market in the past 5 years.
Everything from separate lightsources, CCFL tubes, failing inverters and
LED kits with gaps and warranty issues with vendors. What happens when you
can't find something for your BMW on the market that suits your needs?
You simply design them yourself.
Introducing aurora, an entirely redesigned angel eye kit for your BMW from
eas - unlike anything else on the market.
aurora produces a fully uniform look using a 60 LED array, which matches
most Xenon maps for an OEM look and are very bright - these can even be
seen in daytime. You will immediately know another vehicle with a set after
yours are installed.
