Its the small orange one... I don't know what it's function is, but I noticed its out....

 

Of course it's replaceable! My dealer replaced mine for me under warranty. Pretty much all light bulbs are replaceable in the G with the exception of the LED taillights...you'll have to replace the entire LED assembly.

The orange light is known as the parking light...http://www.wisegeek.com/what-are-parking-lights.htm

 

yes its replaceable with #194 led bulbs if u like through the wheel liner.

 

Cool... I wanted to make sure cause I knew that the tail lights are not replaceable (talk about stupid engineering) so I was hoping this wasn't the same.

Warranty covered it? Kinda surprising... thought it was a "wear and tear" item

 

Fwiw - it's called the Clearance light/front side marker light and the replacement bulb info can be found in the owners manual, section 8.
That one is a 5W bulb, # WY5W.

 

Yeah, I noticed the light wasn't working the day I bought the car, so I would guess warranty would cover something like that.

Shouldn't be too hard to replace, considering I replaced the HID bulbs myself without taking the tire off and going through the wheel well...

 

yes,they may be expensive and hard to replace, but the lifespan of leds are phenomenal, never seen broken led tail lamp on any car any model.
As you dont need to replace it, whats all the worry about.
this is like complaining inaccessible engine block, you never gonna worry about it, will u.

 

^ the worry is justifiable due to the fact that we already have had 3 ppl on just this section of this forum alone with the burnt out leds in their rear lights requiring new taillight assemblies and luckily all 3 were under warranty, had they not have been it wouldve been a lot of $$$ to spend for fixing cause of one led going out.

While leds do last a LONG time and most probably for most of us we will have changed our cars before they die, there are many cases where tail lamp leds go out on many different model, perhaps you havent seen any cause you have never really looked for em but if you do you will find them
