Here's the bulb chart, which lists the wattage.

Thanks josh. Is there any corresponding bulb size?

Thx

You mean for the map light and dome light? The stock bulbs don't have an exact match in American parts stores, but DE3175 bulbs should fit and are very slightly brighter.

yes, i'd like to switch them out to brighter LED map and dome lights.

reverse/backup light bulb size would be nice too.

thanks again.

The reverse & backup are listed in there as well.

Happy to help.

The reverse light bulbs are 1156 bulbs. Definitely do not put those aftermarket LED things in your reverse lights, though; the beam pattern will be all wrong. This isn't as big a deal for the interior lighting, but you really don't want to screw up the beam pattern of a light that you use to see where you're going.

To upgrade your reverse lights you need a bulb with the same base and filament location as the stock bulb. There are three good options:

3497 bulbs are about the same wattage as 1156 but are krypton filled so they produce about 40% more lumens. I actually replace pretty much all 1156 bulbs on my cars with 3497 bulbs.

796 bulbs are about 30% higher wattage than 1156 but are a lot brighter (twice as bright, in fact) because they're halogen bulbs instead of regular tungsten incandescent. If you go with these, you have to be careful not to leave any oils from your fingers on the glass, because it'll make them burn out a lot faster. You'll probably have to touch the glass to install the bulbs, so wash them with rubbing alcohol afterwards.

Finally, there's the 795 bulb. It's about twice the wattage of the 1156 but puts out about three times as many lumens. Again, it's halogen, like the 796. It's a little iffy to put such a high-wattage bulb in your reverse lights because they draw so much current and generate so much heat (they're actually higher-wattage than your headlights' low beams).

In my cars, I've been using 795 bulbs for years. I figure that I don't usually leave the car in reverse for more than maybe a minute tops, so the heat won't be a problem. So far, it hasn't.

You can buy 3497 bulbs at any auto parts store. 796 and 795 bulbs are a little harder to find because they're intended use is for warning lights like on police cars or plow trucks. You can find them online though.

That's good info Vikash!

Thanks

You're welcome. And while we're at it, the 3496 bulb is the dual-filement counterpart to 3497, so you can replace the 1157 bulbs in the brake/tail lights with 3496 bulbs to make them brighter. And the wedge-type bulbs like in the license plate light and the post-facelift sidemarkers can all be replaced with brighter 2825 bulbs.
