Took a quick spin tonight. Was running in low gear up a hill at around 5000rpm and nailed the throttle. Both low beams went out at the same time and the check engine light on the cluster came on for 2-3 seconds and went off. High beam still worked (and I have a light bar). Got home no problem. Check fuses, relay, etc. With no issues. Looked at the bulbs and both left and right are blown. seems odd the fuse didn’t blow, but I guess the fuse is rated for all 3 lights and with only two on, a power spike wouldn’t kill the fuse.

Anybody have this happen? Everything seems to function fine now. I just ordered some new lights. What could be the issue?
