nissan sentra 2004 dashboard illumination

Hi, I've recently purchased some T5 blue LED bulbs to match with my Pioneer CD player I've installed. There are 2 different socket colors behind the meters and according to Nissan's service manual, the brown ones are 1.4W sockets and the black ones are 3W sockets. The problem is, the LED bulbs I've installed only light up in the brown sockets . Is it possible to get bulbs that will light up in a 3W socket? Thank you very much for your help!

I think I've already tried but I'll be trying again today. The real problem is, the bulbs I have measure 20mm or so and the old incandescent ones are about 17-18mm. I think I'll have some trouble because it looks like I won't be able to lock the little V2 sockets. But anyway, thank you very much for your help!
