Upon landing in LGA and taxi to gate instructions where; 'Taxi to gate via Sierra; Papa; Bravo; Lima; enter Ramp 9 Alpha to gate.' Making transition onto Lima and then towards 9 Alpha; the southeast corner of the unlit paved 'island' between Spots 20 and 23 can become a taxi hazard late at night; especially during inclement weather. The 'island' is unlit. LGA's islands have 1' diameter by 18' high; unlit; vertical poles painted blue on the top half. The blue color blends into black asphalt at night and is very difficult to see until one is right up on them. Unlit island between Spot 20 and Spot 23 can be a taxi hazard at night; especially [in] bad weather. Please coordinate with LGA Airport on either making the marker lit during night time operations; or removed for possible FOD hazard to taxi operations.
Air Carrier Captain reported there is an unlighted island that is very difficult to see at night or during inclement weather during taxi; Lima between spot 20 and 23; at LGA.
