LEFT SIDE DIRECTIONAL SIGNAL IS BLINKING FAST. ALL LIGHTS SEEM TO BE WORKING. On the older vehicles it meant that one of the bulbs was out. Since the TL has all LED's, I am at a loss. Any suggestions will be greatly appreciated. my Acura is a 2009 TL with 76000 miles. It is still like new.

 

the turn signals are not LEDs? no?

 

Definitely not from the factory

 

I worded that weird...

I meant to say; the TL's turn signals are normal halogen bulbs. they are not LEDs from the factory.
so, yes...A fast blinking turn signal could mean the light bulb is burnt out

 

how difficult is it to access the front parking /directional lights

 

Not particularly easy but not impossible. I replaced mine with switchbacks and I drove the front end onto ramps at home. Remove some plastic underneath to gain access. I think you can also get them from the wheel wells. Turn the wheel all the way in one direction and remove the plastic in the front of the wheel wells to gain access.

 

It's very easy to drop the front bumper to gain access to headlights.
Any other way is futile
