Dying lights on Bates Motel

I bought this light up Bates Motel sign less than a week ago, and while she lit up beautifully, I looked up to notice that the aforementioned words' lights have started dying (you can see the stark difference between 'Bates Motel' and 'vacancy'

I don't keep this light on an excessive amount, only turning it on when I know I'm going to be working at night and want my prop lights on (I always turn em off before going to bed), and it just felt weirdly quick for this one to already die, considering the amount I've had it on and the fact that I've never had a Spirit prop blip out like this so early

Anything I can do regarding fixes ? Is this a known issue or did just grab a crappy light ?
