Electronics 5001 Strobe Lamp Replacement Bulb

This is the second one I have purchased in 8 months. This is used on top of our maintenance utility vehicle (AKA electric cart) and I expected longer lamp life otherwise I would have given it a 5 star rating. It works fine for a while but I am wondering if there is a long life version of the same lamp. It is only used for about 2 to three hours per day intermittently.
