HB4/HB4 Terminals and Seals

Now you can replace those corroded old terminals  and their seals. This type is stock on Mazdas, Toyota and many other makes.  Corroded terminals can lead to headlights going off randomly and less than full power to the bulbs. If you have noticed any headlight  flickering or going out when you move your bulb socket, you MUST replace these terminals.

If your sockets look like the ones above then you can replace its terminals and seals with these. They will not fit other makes, only Sumitomo. Toyota part number 82998-12550
