Give RX350 HID Lenses and bulbs a shot. Over on the TacomaForums,
crashburn80 has done a few years worth of research into everything you could possibly drop in to a stock housing and nothing beats stock lenses with h9 bulbs in performance over distance but I think the RX350 HID lenses, ballasts, and bulbs can be retrofitted or get a similar kit from Morimotto and give you more lumens for a similar performance end result. If Trucklite hadn't patented a heating element in the lenses of the housing for 8" round lights, all the other aftermarket companies could make something that would work with a proper LED reflector and bulb setup.
