Re: What bulb is in the WK2 fog light?
FYI, when I ordered the H16s a year ago, high performance bulbs said the H16s were the wrong bulb for the WK2 and sent me the PSX24WHPLEDW instead. The PSX24 has the correct base. The two bulbs look like they have the same LED specs and price, so the difference, I think, is just a better fit (no trimming).
2011 WK2 Overland Mineral Gray/Black, Advanced warning, V8; 2009 KK Rocky Mtn V6; 2000 WJ Laredo I6; 1979 CJ7 I6... green... miles of smiles :)
