If your on a budget I have had good results using LED SMD PANELS that can be purchased on ebay. You can get them in 12, 24, 36, or 48 for less than $5. They are simply flat PC boards with led Surface Mount Devices (SMD's) and come with an adapter to plug into the particular fixture that you are using it in (ie 1156, BA9S, wedge Etc.) They usually come with foam tape on the back for mounting but I find that the tape is not the strongest and sometimes an alternative mounting method is needed.
They are plentiful and always available on eBay so I buy a couple of a few different ones try them and if I find that they work for me I then buy more from the same seller.
I have found that The SMD LED'S are brighter than the standard bulb type led's and are more reliable.
Right now I am using these in my interior light fixtures and prefer the light much better than the standard 1156 bulbs and they use much less energy so I do not have to be as conservative with my interior lighting.
My plan is to wire 2 of the 48 SMD units together for my porch light. Should be plenty of light for under $10.
I will try to attach a picture here.
