I finally had some time to go to Concord Customs today to enquire about the inverters for my Angel lights which are supposedly supposed to make them brighter than what they are now.
The guy had a look at it and he said "Looks like we need to open the headlights" which is gonna set me back $250.
But he pointed out below:

That White board is the power source for my angel lights and that needs to be replaced with the inverters I have.
So at this point, I need to find out what power voltage that white board is If it's the same as the Inverters, then there's really no point replacing them. But if they are different, then I'll go ahead with replacing them.
I am literally 1 step away from finding out.
