LED

The new and old distinction of LED is judged by shape.
Even when replacing one old LED, exchange it with two new LEDs and two lenses.
When replacing with old LED Board ASSY, replace with BB-EXP Board ASSY(PCB 2) + tow Lenses(E22).

When connecting to the cover put a 

DOUBLE SIDE TAPE

 on the Lens (E22).
