Got a new to me 2003 Cardinal. Noticed that the interior light are extremely hot. I think it's the 12v lights. Found some 12v led bulbs. Anyone use these and are they cooler

LED G4 replacements will not run hot at all and use dramatically less current than even the Halogen bulbs. Google, " LED G4 replacement ". Lots of choices.

my old 05 actually used 1156 tail light bulbs and they were stupid inefficient. You need to pull one out and see just what bulb it takes. Be aware though some automotive bulbs use a resistor in them and you won't really save anything. They do that so the blinkers function without an electronic assembly and the computer see's the same load as a normal bulb. Make sure you get LED's without the resistor if you are trying to save power Chris

I changed all the bulbs in my TT with LED....32 to be exact....bought them on ebay for about 40 bucks delivered. Much cooler and way less power consumption. I had both T10 and G4 bases

Some LED replacement lights have built-in voltage regulators that allows the LEDs to work over a wide DC VOLTAGE range. These type of LED assemblies are known to produce RFI signals that may interfere with your HDTV, WX RADIOs, and other units like HAM RADIO, Home Scanners, etc...These are especially prone to RFI interference when using your OTA OUTSIDE ANTENNAs that have weaker signals.What most folks will do is buy only one of the LEDs sets they want to see how it worked first before buying 34 of them... Might save you $150 buck or so...You will also have to learn the difference in LAMP WATTs and LAMP LUMENS. The LED items are specified in LUMENS. 250 LUMENS is roughly the same brightness of a 40WATT LAMP. We liked the WARM WHITE Temperature type the best.I ordered the cheap $4.99 LED BOARD from EBAY CHINA first then ended up ordering many in lots of ten after I found out they worked in my setup for even a better deal. This cheap price gave me a chance to have several spare LED boards on hand which I have not used since getting them in 2010. I replaced the automotive type high current and very hot 1156 and 921 bulbs...This was a hugh power savings for us when we want to camp off the batteries off the power grid. I think they say it is around 180% power savings over the automotive incandescent type bulbs.Roy Ken

I checked my bulbs to see which ones, went on to Amazon and typed in led bulbs and you can get the part # cross over and order a box of 10 for $25 to $50 depending on which ones you have. if you are unsure, take a bulb to batteries plus and they can tell yo the cross over. check around for pricing as it varies a lot. i am happy camper without using lots of juice to light up the place! Good Luck & Be Safe ! ! !
