Frequently Asked Questions
Does Legacy Alpha-LH4 have the same warranty as current Alpha Series bulbs?
No. This exact Legacy H4 listing has no included warranty. A lifetime warranty shown on another Alpha Series product does not apply to this clearance item.
Can I return the Legacy H4 bulb if I choose the wrong application?
The existing product notice states CLEARANCE ITEM – FINAL SALE – NO RETURNS/REFUNDS. Confirm the bulb and housing before purchasing.
Can I use the specifications from the current Alpha-H4 product?
No. Alpha-LH4 and Alpha-H4 are different SKUs. Do not transfer the current product’s wattage, voltage, output, package quantity or warranty to this Legacy listing.
Does this bulb product replace a complete factory LED headlight?
It is intended for a compatible serviceable-bulb application. A factory LED assembly can have integrated electronics and light sources that do not use a replaceable bulb of this type. Inspect the installed equipment first.
Will these bulbs prevent every dashboard warning or flicker?
Results depend on the actual lighting circuit and connections. Diagnose any warning or flicker before selecting an additional module, and check the physical lamp application separately.
What should I check before fitting this bulb?
Compare the mounting and retaining arrangement, connector and space behind the lamp. The original dust cap must fit correctly, and cooling parts or attached electronics need adequate clearance. Check the final beam aim after installation.
