Fog and reversing light cut can solve the housing mismatch problem, eliminates the installation errors.
Since around 2018 year, more and more Japanese cars started to use new standard housing bulbs(L1B fog, LY5B turning, LW5B reversing) instead of previous fog lamps(normally H11, H1) and reversing, braking, turning lamps(usually S25(1156/1157), T20(7440/7443), T25(3156/3157)). At the beginning these new bulbs came with small cut housing, in recent couple years, big cut housing bulbs appeared in the market too. These L1B fog, LY5B turning, LW5B reversing bulbs are often used in the new cars of TOYOTA, LEXUS, DAIHATSU, SUBARU, HONDA, etc..
