Got my hayride wagon finished. Wired up some LED flashing warning lights for safety. Need to upgrade the lights on the WD45 now. Anybody know of any plug and play replacement bulbs? I have 6v GE1133 right now. Anyone have any experience with this? Thanks in advance!

I've been using these for years on my CA.

I sure did not know they make 6v led bulbs. Learn something new every day.

White LEDs are actually about 3 volts, so 2 are in series to make 6 volts, 4 for 12. Depending on make/model of LED though some use 3 in series for 12 and a small resistor to limit current. Those good for 6-20 volts probably are run in 'constant current' mode which is how LEDs are supposed to be used.

You can’t merely string 2, 3, or whatever LEDs together to get to a12 volt total. You need a current limiting resistor, regardless of the voltage. In the case of using 6 volts for a 12 volt light, you would need to change the value of the resistor. It’s a little more complicated than just installing a resistor of half the value. You tell me the voltage and current rating of each LED and I can calculate the size of the resistor needed.

Try these: https://www.digikey.com/products/en?keywords=CL25N3-G-ND" rel="nofollow - https://www.digikey.com/products/en?keywords=CL25N3-G-ND

will operate on 5 to 90VDC, and output .025mA. They are also available in .010mA, .020mA, in both the TO-92 package, as well as SMD.

Looking for a complete plug and play bulb.Just twist it into the socket and go. Dont want to do any wiring or resistors, etc. Keep it simple

Finding something for 6 volts will not be easy. There are LED's out there that can be made to work on 6 volts, but finding a plug and play one might be a problem, at least finding one with 50 equivalent watts or more. Look around. Google. I might be wrong.

I ordered what DennisA IL suggested. Will report back when they come in and I get them installed.Thanks for the help!

Make sure your flasher will work with LED's. My sheriff's department got this wild hair that they wanted LED's for their tail and directional lights. Net result: They wouldn't flash unless we installed resistors in parallel with the bulbs. The current draw was too low to perk the flasher. Finding a LED flasher for a 2014 vehicle was next to impossible.

LED bulbs are POLARITY sensitive - so you need + or -- ground bulbs . They just don't work without proper polarity . Seems I found out with British motorcycles as they are + ground .
You can find bulbs on AMAZON that will work

The 1133 white LEDs as posted by DennisA above work fine in any 6 Volt system,either + or - ground, they are what you want, just plug and play!!! Pay no attention to the other posts above, they do not apply to this situation!!!

I am interested in hearing how it works out! May need to order some myself.
