Ceramics Interior/Exterior LED Light Super Stable and Bright Bulb Bayonet BA9 BA9S 53 57 1895 64111 T4W Size Ice Blue Color

A lot brighter then the regular bulds

I had to replace the marker lights on my 1970 Roadrunner trailer. Initially, I was going to replace the old lights with LED Markers but due to the cost, I decided to replace the bulbs. I was impressed with the brightness of these bulbs, and the cost was much less than buying them at Autozone.

Used these bulbs on a rear marker light upgrade. Of the five original marker lights only two were functional and most of the lenses were cracked. These lights used the push-in 193 standard bulbs. The sockets on the non-functioning originals could not be salvaged, as these units are riveted in place changeout was required. After seeing these red bulbs I found Grote makes a dual bulb marker light which required a wiring change so that the polarity is correct for these LED bulbs. You can see from the picture that these bulbs are very bright compared to the standard bulb rear lights. The RV is a ‘96 Fleetwood Southwind.

Great upgrade. Retrofitted these into the dash lights and shifter indicator on a 1965 Mustang. Good color combination for factory dash. However, they don't work on the (combined) turn signal indicator on that particular vehicle as it has a reverse polarity on one of the directions but this is a vehicle specific issue not a bulb issue. Also, since they don't have any significant electrical load to them, the dash light dimmer on the headlight switch doesn't work. A person could put a load resistor in there if they were willing but I'm fine with bright dash lights.

Cheap but still functioning a year later

Bought this time for a Triumph, but it is having its electrical system switched to negative ground, anyway. These are just about perfect for dash and meter lighting.

I used these to replace the instrument lights on my 40 year old Honda GL500 motorcycle. They are perfect for the backlights of the speedometer and tachometer, but are so bright that I had to use the ND6 gel (see https://www.amazon.com/dp/B08818V6Y2/ref=cm_sw_r_cp_apa_glc_fabc_TNNR007REJJ6Z4PJ0BMW?_encoding=UTF8&psc=1) to reduce the brightness for the turn signals and neutral light because at night they were blinding! I have been using them several weeks now and they are working great! The pack of ten was great because I needed 9 lights altogether. I love the white light in place of the incandescent yellow of the original lights!

Just leaving bread crumbs for other restorers. These will replace the #53 / ba9s gauge lights in Datsun 240z, 260z, 280z S30 cars. The rheostat dimmer works with them in my 260z. I removed the green tint lenses from the gauges, but I believe these would have fit inside the lenses, although I do not know if their temprature would damage the lenses. These are lighter color, which I wanted, but others may not (if not, just find some good tinted bulb covers). I do not know the longevity, but these seem to be good bulbs.
