I ordered 19 of these LED bulbs to replace the automotive-type "1141" incandescent bulbs in our 2005 19-foot Bambi, including all overhead fixtures, the closet, the (exterior) rear storage locker, and scare and porch lights:
Amazon.com: LED 2W 12V White Omni Bulb BA15S 1156 P21W Brake Tail 18 5050 SM: Home Improvement
I also ordered one of these LED bulbs to replace the C921 incandescent bulb in the stove exhaust hood:
Amazon.com: LED 18x5050 2W 12V White Omni Wedge Bulb T10 194 168 2825 W5W: Home Improvement
These LED bulbs are "warm white" and fit in the existing fixtures, including the porch/step light and the scare light. The LED assembly is a little bit longer than the glass envelope on the incandescent 1141, but the LED bulbs fit in all fixtures with no interference.
The LED color and brightness are almost exactly the same as the incandescent bulbs, the only difference being that the LEDs are very slightly brighter. Also, the LED bulbs run much cooler. (The incandescent bulbs get hot enough to burn fingers after being on only a few seconds, while the LEDs are just warm to the touch after 15-20 minutes.)
Both LED bulb types were $4.99 each, and the shipping charge was $4.90 (as of 09/2013).
I placed my order online via Amazon.com, late Tuesday afternoon; and I received the LED bulbs on Friday (shipped via USPS from Florida to Arizona), which was 3-6 days ahead of the estimated delivery date.
One bulb had a row of three LEDs that did not illuminate due to a missing solder joint on a miniature printed circuit board that is part of the bulb assembly. I sent a message to Eversale.com (the seller) via Amazon.com late Friday night asking if it was OK to attempt to repair the bulb by soldering the circuit board (I didn't want to void the warranty), or whether they wanted me to return the bulb for a replacement.
Eversale.com immediately shipped a replacement bulb early Saturday morning, and I received it on Monday. They also said that I could attempt to repair the defective LED bulb if I wanted to. However, it was unnecessary to return it. I soldered the miniature printed circuit board, which fixed the defect; and I got an extra bulb for free.
When I offered to have Eversale.com charge me for one more bulb to cover the cost of the replacement (since the defective bulb now worked), they said to keep the extra bulb as a thank you for my order; and they apologized for any inconvenience.
I can't believe how quickly Eversale.com processed my order the same day, responded to my messages, and immediately forwarded a replacement. I'm also amazed that the US Post office managed 2-3 day "standard" delivery, with the second shipment occurring over a weekend.
Good customer service is rare, but it's alive and well at Eversale.com!
