W4 - 12V 10W BA15S Halogen Light Bulb
Bright Idea for Your Indicator Woes
The 12V 10W halogen bulb with a BA15S base is the unsung hero of your motorhome or caravan lighting setup. Small, reliable, and ready to shine when things go dim — quite literally.
-
Perfect Match: Designed for use in indicator lights, with a BA15S single-contact bayonet base that slots in like it was born there.
-
Just in Case: Keep one (or two) in your spares box — because bulbs never blow when you’re parked up, only when you’re 100 miles from home and it's starting to rain.
-
W4 Quality: From the trusted name in caravan accessories, known for kit that actually lasts (and doesn’t cost the same as your gas bill).
-
Energy Efficient: Halogen tech offers bright light with minimal power draw — perfect for 12V systems and battery-conscious campers.
-
Road-Trip Ready: Compact, dependable, and essential for legal, visible, and stress-free touring.
Because when you’re reversing off a pitch or signalling at a junction, you want to be seen — not just waving your arm out the window like it’s 1953.
