Did anyone end up upgrading their interior and exterior bulbs to Philips Ultinon LED? I rushed through an order and upgraded everything interior and exterior w/ Philips Ultinon LED but didn't realize the disclaimer saying that I might need LED Adapter CANbus for every bulb. After factoring in the new costs plus shipping costs it's going to cost more than I'd like so I think I might just return everything and stay away from Ultinon LEDs. Thoughts and recommendations??? 2012 G37x AWD Sedan

 

You do not need any CAN adapters for the G37. These cars do not monitor bulbs like (my) BMW and other premium makes.

 

Thanks for the save, almost had a heart attack!

 

One place that could give you trouble are the in-cabin / map lights. Because that circuit is designed to fade out incandescent bulbs, LEDs in that spot may not dim all the way.

 

But there are reports of hyperflashing... wouldn't the fix require adapter in the end?

 

Is this something that people just get used to?? I can't imagine modding it just to get it fixed??? Any1?

 

What about the exterior LED lights???

 

The G37 does NOT use any CANBUS-type bulbs- interior or exterior.

 

so you're saying all and any LEDs will work on the g37... despite reports of users experiencing hyperflashing or error messages??

 

That is not what I am saying. I am saying that you do not need CANBUS "error-free" specific bulbs as the G37 does not monitor lighting on the CANBUS network. CANBUS is a communications network. CANBUS bulbs/ lighting modules "talk" to the network and do their thing. When a bulb (LED or incandescent) or module goes out, the network notices that the affected unit(s) stopped "talking" and sends a alert to the driver.

The hyperblink occurs when the BCM notices the load difference in the circuit. When incandescent turn signal bulbs fail, the load on the circuit drops. As a result, the BCM notices this drop and will "hyperblink" the bulbs as well as the turn signal indicator (on the affected circuit) on the gauge cluster. as a means to alert the driver a bulb is out. LED's, because they do not draw as much current as incandescent, "confuse" the BCM into thinking a bulb is out.

To correct the hyperblink a load resistor is usually needed. This resistor (usually 6ohm) is NOT the same as the CANBUS error-free rating (usually 60 or 120ohm). Most reputable places will include the resistor if you need one when you order the bulbs but, always VERIFY BEFORE YOU BUY.

 

This is what I hate about our cars. No bulb out warning. You know how many times I've been driving over the years with a blown fog light, taillight, or headlight and didn't even know it? My 2000 Volvo S70 would let me know a bulb was out. Also hate that it lets me close the sunroof shade while the sunroof is in the vent position. My Volvo wouldn't

 

I drove 4 months without knnowing..... even the cops wouldn't pull me over to warn me. That's how un-obvious it was. My eyes are also bad/streets in Toronto arre mostly well lit so I guess I couldn't tell the difference at night
