Re: 12 LTD headlights under Warranty... Otherwise $250-$350
What was wrong with them?
Bulbs and ballasts are fairly cheap, you could buy higher quality bulbs for $50 or so online. Ballasts tend to be the pricey side of the whole deal.
FWIW, HIDs are supposed to be "lifetime" parts. My $40 DDM kit lasted 5+ years without issue, if Jeep's can't last over 3 years they really need to get their quality in check.
