I have been using these lights (1157 bulb) for 8 or 10 years (or longer) with no problems. My son talked me into going to LED replacements, so I did, and within 3 weeks the individual LEDs started malfunctioning. I don't think the technology is there yet, with LEDs, (because of the heat dissipation & condensation) to enable long life. So I am back to incandescent and halogen bulbs. Newer is not always better. Thanks for the great product. P.S. Our 4 wheel drive club is getting away from LEDs & going back to "old school lights".
