What's the brand of OEM h11 low beam bulb? I am trying to check if I can find a better white bulb for it instead of change to HID.

 

looks like its made by KOITO

 

Looked at this, looks like it's white and bright. May not have any improvement if I change to another one.

 

Just go with H11 to H9 bulb conversion.
Regular H9 bulbs cost less than $20 a pair which is at most 1/2 the cost of any high performing H11 bulb for the same light performance.

Either bulb burns out in 1-2 years so the cost difference adds up over time.

Or do what I did and do a HID conversion, $125 and you're done ... HID bulbs go out in 5-6 years.

 

Yep, it's hard to get significantly 'better' without sacrificing lamp life. I replaced the OEM lamps in our XC60 with the whitest and brightest without getting something that would fail in a matter of months. The light looked 'clean' and 'fresh'; but hardly a significant difference.

 

I replaced my other car with philips bulb, they are very good and long lasting. But I don't think this rdx needs replacement, it's already white and bright. The quality of SYLVANIA is very bad.

 

How difficult to install HID? I am very busy not have a lot of time.

 

Depends on how neat you want things done.
Should take about 2 hours.
The DIY section has a couple threads on this.

 

The only vehicle I've had with HIDs before the RDX was a 2002 Infinti QX4. I bought it new and traded it in on the RDX 10 years later. Never replaced a headlight or any other light bulb on the vehicle for that matter. Can't ever remember having a vehicle that long without replacing a few bulbs. Lucky I guess.
