The 08E13-TZA-600 LED lamp is a straight swap for the standard filament lamp, inserted into the existing lamp holder.
The Honda dealer I purchased mine from mentioned it was just a lamp, rather than a new light fitting, possibly to reduce the shock of discovering the cost for merely a lamp! He stated they’ve been selling quite a few of them. The cost through the parts department is less than the quoted fitted price and no other changes are required. Just replace the old boot lamp for new, as per the procedure described in the owner’s manual.
