I suggest you check out Tayda Electronics. I am a happy customer with many orders placed with them. They are based in Thailand but have US stocking of many of their products, with delivery often being a week by USPS Priority Mail.
I have found most of what they sell to be of good quality, usually with datasheets and full specs being available.
The water-clear ultra bright are a great deal. Just be careful, I had one lot from Tayda with the anode/cathode flipped vs previous batches (only happened in the Red Clear so far). Everything in the bag was the same so I didn't have to check each one but that one batch was annoying.
They are very bright and only need 5mA, 100uA in some applications.
also, they are very red in real life but look orange in photos because they seem to saturate the detector on the camera. Turn the camera brightness way down if you want the LED to appear red.
I have to rebuild all my LED PC boards all the metal wires rusted off the, resistors, transistors, LEDs. I had PC boards & D batteries in zip lock plastic bags but they all full up with rain water. I tried different zip lot bags they all leak water. Now I have melted a toilet seal with equal about of candle wax then pouring it on the PC boards to make them water proof. I rebuild 2 PC boards yesterday and 1 today. I am out of D batteries bag full of water shorts them out new batteries they are dead in 2 days. Rain won't stop Dec 31 weather man said 64.34 inches of rain for the year of 2019. Finally no rain today but more rain for the next 4 days. I need to hermetically seal these boards & battery in something better that plastic bags. Glass pint & 1/2 pint mason jars will work but 2 D batteries taped together side by side won't fit in
You've found that zip lock bags aren't an ideal 'enclosure', but if they are filling with water you likely have the zip lock facing upwards.
How about inverting them?
Attach some duct-tape to one corner, with the zip lock facing downwards.
Hang the bag from the duct-taped corner and put the flasher inside, but leave the lowest point of the zip slightly open.
This should allow any water that has gotten into the bag, from unseen holes, to drain out.
I have many cheap Chinese solar garden lights. The old ones used a solar panel with a plastic cover that got sunburned after being in the sun for a couple of months but new ones use a solar panel with a glass cover that lasts for years.
The cheap Chinese LEDs, transistors, resistors and Ni-CAD batteries rusted away in a couple of months from rain leakage or condensation. Wire made from old tin cans is cheaper than copper wire. I replaced them all with Western parts that use proper metals that do not rust. Newer solar garden lights use batteries marked Ni-MH but their capacity is 1/4 what is printed so they might be the same old Ni-CAD ones. Newer solar garden lights replaced the rusting transistors with an IC that does not rust and it performs the charging and voltage boosting. The IC boosts a 0.8V run-down Ni-MH battery cell to over 3V so it can brightly light a colors-changing LED.
Old solar garden lights used a cadmium sulfide photo resistor with a plastic cover that also got sunburned in a couple of months. Newer solar garden lights use the solar panel as the light detector. Cadmium is deadly and is banned in many countries.
