I wonder if anyone has tried replacing the OEM bulbs for the more contemporary LED bulbs that are more vivid and sharp when turned on and off just like other luxury vehicles: Infinity, Mercedes S Class, BMW 7 series. I understand that the front turn signals OEM bulbs are 4157NAK, but I'm wondering if a regular 4157 or 3157 bulb will fit.

 

good question i would like to know too usually the letters stand for a color or something

 

led bulbs would work.. but there is one problem.. its that when u put the bulb in led's suck less power so your vehicle thinks that the bulb is gone.. you need a relay to prevent that but no such one is out yet

 

OH Yeah.... Kash, I had the same problem before with my old Acura TL.
The LEDs became much dimmer than the regular light bulbs.
