Second thing is check the tombstone to make sure the connection is good some case the conductors can come loose from factory which I have see it once a while.
You will need 4 lamps to get this light up first time.
And try to switch the red et bleu socket around some case it will work.
If that fail to light up then take a test lamp or use the tempory outdoor pigtail light socket and use with 60 watt bulb and hook it up tempory to make sure you actually have good source due some of the DVM ( digial voltmeter ) don't actually put a load on espcally with a bad connection which it will show up.
If your test light don't come on then you have issue with supply you may want to check the connection and splices at the junction box ditto with switch box if the netural is there.
