Used one in the traffic light on a Sunday afternoon for a traffic light that came on maybe 3 times a night for 2 minutes and blew by Wednesday evening. He worked like this for about 18 minutes. there was a blown lightbulb so put in another of 10 lightbulbs tonight. If it works for a reasonable amount of time I'll update the review. Review updated as promised. These bulbs are rubbish, out of the whole pack only 2 lasted more than 2 weeks. The rest burned out in 7 days or less. Wouldn't recommend these to anyone!
