Trouble with VHO lights

[toadstar]

My VHO lights is working good until I try to replace two new lights today. After the installation, I turn the switch on. Both light fire a flash and never come on. I try several time, each time the same thing happens. After a while, both lights don't flash no more. Do you think the Ballast goes bad? Or the end cap? Please help. Thanks

maybe you may have mixed up one of the end caps and it is causing the ballast to short out.

what kind of ballast?

Recheck the wiring. Push & pull each wire in the endcap as well.

Thanks for your help. I have received a defective light buld from BigAls.com. I follow your instruction and somehow get the set to work with the old light buld again. When I put the new buld in, it did not work. The worse part is I could not return the buld because I did not check it when I received it. Thanks again.
