Hey some good looking taillights ideas! I really enjoyed your first design, It looks very modern and aggressive. I've always had a soft spot for custom lighting on vehicles
I came across a page on Instagram that makes extremely custom lighting for practically any vehicle. He has some designs very similar to this, bold and modern. The company is P.LUXE and I think they do a great job.
Just something I happened to stumble upon, not trying to advertise, being that they are running about 1,200 a pair for taillights. A titch out of a budget build range but still very very cool
