Improved Rear Combination Bulb Life
This Pitstop article provides information relating to the improved durability of bulb life for part number 18644 28088N (Rear Combination Bulb: Rear
Stop Lamp/Tail Lamp Bulb) utilized on multiple Kia models. Part number 18644 28088N has a bulb life of approximately 400 hours, the new
replacement bulb part number 18644 28088L has a bulb life of approximately 2000 hours (long life bulb). Kia has already phased this change from the
factory for part number 18644 28088L on the current model line(s). In the event that the old part number 18644 28088N is in need of replacement, both
the left/right-hand rear combination bulbs should be replaced together with part number 18644 28088L (Long Life). Failure to replace the rear
combination lamps together could cause customer complaints for multiple repairs and bulb replacements.
Bulbs can be identified by the markings on the base of the bulb: 18644 28088N (old part number)/Bulb base markings: KHA12V28/8W2357637. 18644
28088L (Long Life) Bulb base markings KHA12V28/8W2357LL637 ("LL" is designated as long life bulb).
