Frequently Asked Questions
Does this AlphaFit bulb have 15W dim and 20W high settings?
No. This is the original 14W AlphaFit bulb. The 15W dim and 20W high specification belongs to the separate single-color AlphaFit Gen 2 bulbs.
Can the original AlphaFit run on 24V?
The specification for this exact original bulb is 12V. Do not use a Gen 2 voltage rating as confirmation that this bulb supports a 24V supply.
Is the glass watermelon housing included?
No. This product supplies one replacement AlphaFit LED bulb. The glass housing and mounting hardware are separate.
Can I put it in a two-color Glass Is Class Duo light?
This bulb is listed for the matching single-color Glass Is Class housing. It is not the two-color Duo replacement; compare the exact bulb and housing generation.
Is this an H11 LED headlight bulb?
No. Its H11-style base serves the matching auxiliary watermelon housing. It is not offered as an OEM headlight replacement.
Does no CANBUS module mean it cannot flicker?
No. The specification says a CANBUS module is not included. That is not a guarantee against flicker or electrical warnings in every installation; check the supply and the exact lighting circuit.
What warranty applies to this original AlphaFit bulb?
The current product specification provides a 6-month limited warranty. It is separate from the warranty offered for newer Gen 2 products.
