Headlight unit brown connector

[csabecki]

Hi,
I've been wondering what is that brown connector secured by electrical tape behind the left headlight unit (xenon) in my 09 8th gen Accord.
Can someone help me to find out?
Thank you!

When upgrading my headlights I never spotted anything similar on mine but I only have have halogens.

Being only fitted to one side I'd guess it was aftermarket especially as it isn't in the black conduit
