You don't have to be rude I'm disabled so unable to fix. Besides the bulbs blue as far as I can tell. It's a topfin led lights for a R04075/W 5 strand.
I am sorry if I appeared rude, that was not my intention at all. With most things electronics it is a simple matter of convenience. If you buy cheap, then you get cheap. Usually the cost of repair (time and money invested - parts and labor if you need someone else to do it) gets very expensive the cheaper the item is to begin with compared to simple throw in trash and buy new.
What you have is a black plastic hood that covers the water of the fishtank with buildin led lights? And it came as a complete kit - fishtank, filter, plastic hood with lights? Then unfortunately you are out of luck short of buying a complete new hood with lights. Petsmart will happily sell you that - at a relatively high price.
In the long run it is better to have your lid of the fishtank (to prevent fish from jumping out, less evaporation, help keep foreign objects out of the tank) seperate from the lights. It is a judgement call as it would be more expensive to get glass lids and a new lightbar on top. Down the road you will be glad when either your light goes out again or you wish to upgrade to a better lighting or simply ADD additional light. Most any aftermarket light will do if you have glass lids.
Another option: retrofitting a different light into the existing hood. That is only a viable option if you are willing and capable of tinkering. This is probably the cheapest way, but you will need some DIY knowledge and skill.
I personally try to go as cheap as I can considering follow up costs as well. Best bang for your buck in LED fixtures is probably hands down Beamswork. Cheap and no frills, but still reasonably reliable. Next step up is Finnex - they make some really nice lights with more features (compared to Beamswork). Price a bit more expensive, but still quite low compared to "real" brand name lights. One big advantage of Beamswork is size - they do make 5 and 6 foot long led lights while Finnex only goes to 4 feet. Disadvantage of both Beamswork and Finnex is that you have to order them online. I am very happy myself and had no problems with Beamswork, Finnex, Fluval, and Current USA led lights.
For glass tops - best to have a hinged top that has a strip of plastic in back so you can cut out exactly where a filter or cord would stick out of the tank. Brand really doesn't matter as long as it fits. If in doubt get the ones from the maker of the fishtank. My choice for glass tops is Deep Blue - yes, on the expensive side, but so cool with clear hinges to let more light in (most other brands use black hinges).
