Star / SVP ULB9 Flashback Shield
This flashback shield attaches to the Star Mini-Phantom dash lights.
It will work with either the Star ULB9 or ULB9S.
(The ULB9S Includes a flashback shield in the box, the ULB9 does not)
This shield reduces the amount of flashback of light from the ULB9/ULB9S onto the dashboard
