Need Headlights

I work for a company about to produce a line of small vehicles for the north American and world market and I need headlights. We are looking for either a 24 volt or 48 volt small teardrop lamp assembly, for example 8" to 10" long by 6" to 8" high and convex curved. Our preference is toward LEDs. Please send by e-mail any particulars for example, size/specifications, are they sealed units? or do they require separate bulbs? We require OEM pricing for 1,10,24,50,100,500 and 1000 units, shipping times etcetera. You might consider sending us one or two pairs for inspection. Our body molds will be influenced upon our lamp choice. Non-disclosure agreements will be provided at your request and will be expected in return. Thankyou.
