Another nice feature of these bulbs is that the connector is reversible. So if you plug in the connector from the RV and the light does not work, simply unplug and flip it around. This changes polarity and solves the issue... no need to cut the wire like on some other bulbs. I also found that putting a small amount of dielectric grease on the flange made it easier to twist the bulb in the socket. Just be careful to use a small amount and don’t get any on the bulb.
One of the low beam 9006 bulbs has failed. Not sure but it might have been from driving in a heavy rain storm. The RV does not have much protection for the bulbs as they are located very low on the front.
