There are many types out there, most of them are direct fit or offers accessories to fit your car.
cheapo $10 one doesn't last long and very dim as it only has 2 LED diodes, the only I bought claimed to be samsung chip 4-sides LED, they were $50 in China. I have been using them for 3 years, no problem at all, very close to our Toyota LED brightness (photo can't justify).
