Its up to you chap. I had to re open mine back up due to misting. I then bought a specific headlight sealant made by nissan but it is £28 per roll but it easily does both headlights. I managed to get mine from a chap off ebay and paid £15. I still have some left but not enough. Are you thinking of painting the lights black aswell? Also if you buy them lights that i have linked to, the inverters they sent me werent powerful enough so I had one bright ring and one was dim, but they were very very helpful and sent me out new ones. So I would imagine they should have changed all of the kits to suit. Best to check before installation though.
