Package includes 6 NeoWedge T4.2 LED bulbs for aftermarket (not OEM) HVAC AC / heater controls. 

Check pictures for fitment. 

Check your HVAC unit before ordering. 

These will NOT fit the OEM HVAC unit. Only fits newly produced, aftermarket HVAC units with non standard illumination. If your HVAC unit has twist lock bulb holders that look like the photos, these are the correct LEDs. If your unit has glass bulbs that are removable from the bases attached to the HVAC units circuit board, these are NOT THE CORRECT LEDs. Returns are NOT accepted.

LEDs are polar and will need to be flipped 180° if they do not light up. Check for polarity issues before reassembly of the unit.
