incompatible on '04 Accord
For some reason they went with a design that forces you to use different turn signal sockets/bulbs that unbalanced the circuit and caused the signals to blink fast as though a bulb was burned out. Another reviewer said he got it to work by grinding the hole out to fit the originals, but I don't see any need to be messing with this on a brand new item. So Honda Accord owners beware. Also, overall construction seemed pretty cheap compared to the OEM.
