Well,
I'm another fan of www.superbrightleds.com. I've used them for all of my purchases. Yep, they're a tad more expensive but, mine have always arrived in about 3 days. It's a very educational site. They tell you everything there is to know about LEDs and, how to compare what you have to what you need. The first thing you need to learn about LED replacement bulbs is, what kind and how many "bases" you have in all your intended replacements.
By that I mean, there are several different kind of bases of bulbs, supplied in todays and, yesteryears coaches. One of the most common is the 15mm. That's the one used for decades in the rear of most automobile tail lights. You know, the kind that you push and twist into place.
In superbrights website, they call it a "BA15". That stands for Bayonet-15mm base. Then there's BA15SC or DC. SC= Single Contact (one contact at the tip of the base, and DC = Dual Contact, or, two contacts at the tip of the base.
Those are just examples of the types of bases they sell. There's at least a dozen more. So, if you're intending on converting ALL of the interior and exterior (including compartment lights) then you need to make a list and, possibly draw pictures of where the individual bulbs go and, the type of bases they have.
Then, there's the lumens. You need to learn what kind of lumens the stock bulb puts out then, you'll be better educated when it comes time to comparatively shop for replacement LEDs. Then, there's the "Cool white and Warm white". The main difference is, the Cool white is way closer to a bright, almost a tinge of blue light. Whereas, the Warm white is more of a yellower, softer light.
Stock lighting is closer to the warm white. The gauge they use is called CCT or, Color Core Temperature. It's typically represented in Kelvin. The number scale they use ranges from about 3000K, which is close to the average headlight brightness and color, to around 6000K which, is more like the ultra-white, almost bluish tint on the headlights you see on the newer cars etc.
Then, there's what's called SMD LEDs. SMD stands for "Side Mounted Device". They don't look like a regular, cheap LED bulb found at Auto Zone or Pep Boys. They have little yellow dots on them that light up. It's the more advanced style of LEDs.
So, as you can see, if you get into it, there's a bit to learn. But, it's kind of fun, depending on your outlook. SuperbrightLeds.com is very informative as to what kind of light, how it is displayed, the degrees of spread, color and more. I've not been dissatisfied yet, with more than I care to admit in dollar amounts. It is what it is but, I burn way less juice and my house batteries are really thanking me.
